Suggested March 2024 How To Integrate Google Calendar To Thunderbird

Note: The Thunderbird version used in this tutorial is version 7.01. If you are using older or the bleeding edge version, I can’t promise that this tutorial will work.

Setup Calendar in Thunderbird

Out of the many calendar add-ons in Thunderbird, Lightning is the best. It adds a full feature calendar system to Thunderbird and it integrates so well that you don’t even see the differences.

2. Install Lightning. Restart your Thunderbird.

Integrating Google Calendar to Thunderbird

Now that you have set up Calendar in Thunderbird, the next step is to integrate Google Calendar to Lightning. Provider for Google Calendar is one good add-on that can get the job done.

2. Next, open your browser and login to your Google Calendar account. Go to “Calendar Settings”.

6. In the next window, select “Google Calendar” and paste in the link that you have copied earlier.

7. Give your new calendar a name and set the color.

8. Enter your Google username and password. You might want to check the box “save password in Password manager” so it won’t prompt you for password in the future.

9. Lastly, once you see the “Your Calendar has been created” message. You are done integrating your Google calendar to Thunderbird.

Repeat the same steps for each and every Google Calendar that you want to add to Thunderbird. The “Provider for Google Calendar” supports a two-way sync, so you can add/edit events and tasks in Thunderbird and have them synced back to the Google server.

That’s it. What other ways do you use to integrate Google Calendar to Thunderbird?

How To Fix “An Error Occurred While Sending Mail” On Thunderbird

Don’t know how to fix “an error occurred while sending mail” on Thunderbird. Check out this article to know the proven solutions.

You can use Thunderbird to enjoy the services of various email services like Outlook, Gmail, and Yahoo. While this desktop-based email client is free of cost, it’s not free from errors that you may encounter from time to time as you continue using it.

One highly common Thunderbird error is “an error occurred while sending mail”. This error message usually comes when you attempt to send the email. Instead of sending the email to the recipients, it shows you an error message stating the problem.

This error message can pop up on your screen for different reasons, and various error codes/messages might appear in different scenarios. In all cases, there are some basic approaches you must try. If this happened to you and you’re looking for a solution, continue reading. Here, I’ll tell you what you should do to get rid of this annoying error.

How to Fix “an Error Occurred While Sending Mail” on Thunderbird

Method 1: Temporarily Disable VPN or Antivirus

At times, Thunderbird fails to send email successfully when you’ve got Antivirus or VPNs turned on. The best way to avoid this error is to disable these applications on your computer when you use Thunderbird mailbox for any purpose.

In case you don’t like the idea of pausing the VPN every time you’re about the send the email, you can always ask the VPN service provider for a list of compatible locations or connections. Once you get that, check to find out which one works fine from your computer.

Also, you can go through the process of trial and error to find out a suitable connection by yourself. When you update your Thunderbird, your computer firewall or antivirus software might start blocking you. The reason is it might find the older version of Thunderbird trustworthy but not the updated version.

So, if you get “an error occurred while sending mail” immediately after updating Thunderbird, this could be the reason. To resolve this, you need to remove Thunderbird from the list of trusted programs of your antivirus or firewall and manually add it again. Now, try sending emails from Thunderbird and see if the problem reappears.

Method 2: Try Sending Smaller Attachments

Are you getting this error message on Thunderbird while trying to send multiple large attachments? In that case, these attachments might be the reason behind this error. If it happens, try sending fewer numbers or attachments in one email. You should also try to divide large-sized attachments into multiple parts before sending them.

Method 3: Don’t Send One Email to Too Many Users

Are you trying to send an email to too many users at a time? Besides getting the “too many recipients” error, you might also get this error message. The reason is simple; your email service provider isn’t allowing you to send emails to bulk users.

Try to reduce the number of people you add in the To, CC, and BCC fields. Instead, you can try adding them to a mailing list and send the email to that list. Thus, you can stop getting the “an error occurred while sending mail” message on Thunderbird.

Method 4: Follow the Email Provider’s Threshold

Most email services let you send a particular number of emails every 24 hours. Crossing that limit might result in an error while sending emails in Thunderbird. Hence, it’s better to know the maximum limit of sending emails in a day from your email service provider and act accordingly.

Method 5: Change Email Password

If hackers got access to your email account and have been using it for spamming, the email service provider might have blocked it. And that’s the reason you’re unable to send emails from it. Does it sound like a far-fetched idea? Still, there have been similar incidents that cause Thunderbird users issues like “an error occurred while sending mail”.

To keep your email account safe from unauthorized access and use, change your email password. Now, add the email account to Thunderbird again using the new password and try sending emails to see if the problem persists.

Also, check your Sent Items folder on email to see if you can find some emails that you haven’t sent. Thus, you can confirm whether someone else has access to your account or not. Remember to change your email password regularly to avoid such issues.

Method 6: Use the Correct SMTP Server Settings

SMTP server settings play a crucial role in sending emails from Thunderbird. Depending on the email service you use (Gmail, Yahoo, and Outlook,) you should have different SMTP servers, Port, Authentication method, and Connection Security. You need to make sure that the SMTP server name is correct according to your email address.

For example, if you’re trying to send an email from Yahoo Mail, but your SMTP server name belongs to Gmail, Thunderbird won’t be able to send emails on your behalf. As a result, you’ll get “an error occurred while sending mail”.

Method 7: Confirm That Your Outgoing Email Isn’t Blocked

Is your Internet Service Provider stopping you from sending emails? No matter how alarming it sounds, it does happen in many cases. When it comes to outgoing email port, many ISPs block port 25 and supports only port 587 or 465.

On the other hand, if you change the default port number of an email service provider, it might not work anyway. In that case, contact your ISP and ask them if they are blocking the port. You might also explain the issue to them and ask them to unblock the port.


As stated above, “an error occurred while sending mail” is a common issue for Thunderbird users. Almost every user encountered this error message at some point. There could be different reasons why Thunderbird fails to send this message, and the reason is usually described in detail on the error message with an error code.

No matter what is behind this error, you can follow the methods described here and get the quick resolution to the Thunderbird “an error occurred while sending mail” error. I’ve covered all the approaches that can stop this error message from appearing.

How To Use Google Meet In Google Classroom

One of the more powerful kickbacks from the pandemic was the abrupt and unexpected transition to working from home for millions of us. Solutions to various work-from-home-related conundrums began to emerge in a matter of days even because the level of urgency was so unprecedented. Initially, it seemed like Zoom would emerge as a resounding victor as organizations began using this video calling app as their daily driver for office meetings and team catch-ups. But when major, alarming security issues began cropping up it became clear that Zoom had bitten off way more than it could chew.

So when we began seeing Google Meet whenever we logged into our G-suite accounts, it was only a matter of time before Google integrated this secure, smart, and still-in-the-works video calling feature to all its other major holdings as well, Google Classroom being no exception.

What is Google Classroom?

Launched in 2014, Google Classroom is a hybrid learning tool designed for educational institutions to manage communication between teachers and students. With this service, teachers will be able to create assignments and distribute them to students of a class for teaching different topics and grade them based on students’ performance.

With the educational landscape recently evolving towards remote learning, Classroom is also integrated with Google Meet so that teachers can interact with students easily even from the confinements of their homes. Teachers can create quick meet links inside a class to teach a topic, conduct discussions, and host presentations from students without leaving Google Classroom.

What can teachers do with Google Meet in Classroom?

Of course, nothing Google does is basic. In fact, we are quite fond of them for the thoughtful little things that end up generating big benefits. For a teacher, Meet will undoubtedly be that small thing that manages to have a big impact. Let’s dive into some of these benefits first.

Dedicated meeting links for individual classes

When you’re hosting a class with Google Classroom, you can automatically generate meet links to interact with students in the class and this link will be unique for just this class. Meet links created inside Google Classroom can be used in a recurring fashion, meaning you can use them any number of times in the future as long as it isn’t outdated. 

Interact with a large number of students

With Google Meet integration, teachers can host classes to interact with around 100 students (with Education Fundamentals or Education Standard plans) or up to 500 students (with Workspace Education Plus plan). This can be big enough to accommodate multiple classes at the same time when explaining an in-depth topic or to make an announcement for a large number of students. 

Host live streams with people other than students

If you want to announce something to students and their parents or the school entirely, Workspace users can turn on live streaming to allow up to 100,000 people to watch a Google Meet call. During a live stream, only teachers and other hosts can interact and have their say while the others get to listen and watch.

Record live lessons for later

Meet comes with a Record option which really comes in handy when you’re taking live lessons. You can activate the record option at the beginning of the lesson and Meet will begin recording after taking appropriate permissions and everything. Once the lesson is over, you will receive a media file in the form of a Google Drive link which you can then choose to share with your class.

Gather attendance

Teachers on some Workspace Education plans can receive attendance reports for their students in Google Meet. The attendance report will be sent to a teacher’s email and will include information like student’s name (their number if they dialed into the meeting), email address, the time they were present in the class meeting, and more. 

Moderate students 

When there’s a disturbance during a meeting or if students are misbehaving in a class meeting, teachers can mute them, turn off their video, or remove them entirely from the call anytime they choose to. 

Accept student questions

There is a chatbox that comes as part of the Google Meet interface that really comes in handy to record the questions asked by students. You can even set your meet in presenter view to focus on each question given in the chat and choose to address them accordingly.

Conduct Q&As and polls

Some Workspace accounts also come with the ability to conduct Q&As and polls directly from the Meet screen that teachers can use to see student responses on a certain topic in real-time. 

Make presentations in presenter view

There is also a Present Now button that’s wedged in between the Turn on captions and the three-dot menu icon that you can use to project your screen to your class.

How to create a Google Meet link for your class

For everything else to happen, the link must be generated and ready in hand. The link is basically a unique code for your meeting that you will be able to share with those whom you want to invite to the Google Meet Conference call. So you need to understand how to generate this link. Don’t worry, it’s fairly easy.

For Teachers with Google Workspace accounts

For Teachers with personal Google accounts

For teachers who are not using Workspace accounts, Google Meet isn’t directly integrated inside Google Classroom. So, teachers using their personal Google accounts will have to use other means to create links for a Google Meet call for a class. If you’re a teacher using a non-Workspace account, here are all the ways you can create a meeting link for Google Meet. 

From Google Meet

You’ll now see the Google Meet link appear inside a box on the screen. You can copy this link by tapping on the Copy icon on the right-hand side of the link.

From Google Calendar

To create Google Meet links, open Google Calendar on your desktop’s web browser and sign in to the Google account that you use with Google Classroom.

When this section expands to show all your calendars, select the checkbox adjacent to your Google Classroom classes and uncheck all others. 

From Gmail

Now that you know how to create meeting links for Google Meet, you can now add them to your class inside Google Classroom and manage them from within the class by following the steps below. 

Note: Meet Link generated within Google Classroom is added directly to the class where it was created. So, you don’t need to add them manually inside a class, unless it’s hidden. You only need to add links to a meeting inside Google Classroom if you generated it from elsewhere like on Google Meet, Calendar, or Gmail. 

Make Meet link visible for students

Inside Class settings, scroll down and turn on the Visible to students toggle at the bottom of the Manage Meet Link section. 

The Meet Link should now appear on students’ accounts inside Google Classroom. 

Reset a Meet link for your class

If you’re having issues with a meet link you created inside Classroom, you can get a new one by resetting the current link inside the Class Settings. When you reset a meet link, it will no longer be associated with your classroom but it may still be accessible as an independent meeting. 

Remove a Meet link from a class

If you have meet links inside a classroom that have gone beyond their scope of usage, they will get outdated. We suggest you upgrade these meeting links in such scenarios as outdated links won’t work as you intended and may grant students host privileges. 

Add a Meet link to an announcement

For teachers who don’t use a Google Workspace account, Meet links aren’t generated automatically inside a classroom. Since we already explained how you can create links for Google Meet externally, you will also have to add them manually inside a class you teach. 

Fortunately, Classroom allows teachers to post announcements for an entire class through Class Streams. Teachers can thus, use this section to post a meeting link they created inside Google Meet, Calendar, or Gmail. 

To add a Meet Link to an announcement, make sure you’ve copied the Meet Link to your clipboard from where you create a meeting. 

Add a Meet link to a classwork

Just like posting meet links inside an announcement on a Class stream, you can also add external meet links to the classwork you give out to your students. Before you do that, you need to make sure that you have copied the Meet link onto your clipboard.

Now, choose either Assignment or Question depending on where you wish to paste the meet link. 

How to manage students inside Google Meet classes

If you’ve created a Google Meet call for your class with Google Classroom, your students will be able to join your class meeting. As a teacher, you can control how your students can access the class video meeting directly from the meeting screen.  

Allow students to join a class meeting

Mute students

Lock audio/video for a Google Meet call

While the Mute all feature works to temporarily pause every students’ microphone inside a meeting, students have the freedom to unmute themselves at any time. To avoid constant distractions, you can lock the participants’ audio for as long as you don’t want them to speak by enabling audio lock for all of them. Similarly, you can also prevent participants from turning on their video without your permission by enabling a video lock inside Google Meet. 

Turn on/off screen sharing

Disable chat messages

Teachers can also stop students from cluttering the class’ In-call messages section by turning off chat messages. When this feature is turned off, only teachers will be able to share notes with the class and students won’t be able to interact with each other in the same chat window. 

Remove participants

Bonus Tips

Reset the Google Meet link each time you want to meet with students, this way the older Meet links will not be used unsupervised. You can reset the link for each class from the General Settings of the class.

If internet speed is slow, turn off your camera to improve video meeting quality. If audio quality is poor, you can use a phone for audio, simply make sure that you have the Meet app on your phone as well.

To help students who are deaf or hard of hearing, you can turn on captions using the button of the same name that you will be able to locate easily during the call.

Use these great Chrome Extensions to enhance your Google Meet experience. For example, using the Dualless extension, you can use two windows on your meeting as if you had dual monitors for real.


How To Use Google 2

Most of us use Gmail as our primary email service. So, to gain access to most of our sensitive information, a hacker is likely to launch an attack on Gmail first. Setting a virtually unhackable password is the first step towards immunity.

However, if that password gets compromised somehow, we must come up with a failsafe; one which would keep the hackers at bay. And that is exactly where Google’s two-step verification comes in.

RELATED: How to set up Google 2-step verification

Google’s Two-Step Verification asks you to verify your new Gmail login on your phone, even after entering the correct password. So, as long as you don’t lose your phone and password simultaneously, your account won’t be compromised.

This second step can be a simple Google prompt on your screen, a text message, a call, or even a security key. So, make sure you think long and hard before picking the most convenient option for you. In this piece, we’ll take an in-depth look at Google’s Two-Step Verification, and tell you how to make the most of the useful service.

Use Google Authenticator App

Google Authenticator is a free application that securely generates Two-Step Verification codes on your Android smartphone. No more waiting around for text messages to arrive, simply use the Authenticator app to complete signing in to Google or other supported accounts.

Even after setting Google Prompts/Call/Text/Secure key as your secondary login method, you can configure the Google Authenticator app as your backup.

Here’s how to set it up:

Step 1: Go to Settings and tap on Google.

Step 2: Tap on Manage your Google account.

Step 3: Go to Menu.

Step 4: Open Security.

Step 5: Tap on Two-Step Verification.

Step 6: Enter your password to access the 2-Step Verification menu.

Step 7: After scrolling down and locating Authenticator App, tap on Set Up.

Step 8: Select Android and tap Next.

Step 9: A barcode will be displayed. If you’re carrying out the entire process on your phone, tap on “Can’t Scan it?” to get a code.

Step 10: Download the app from the Google Play Store.

Step 11: Open the app and go to Scan a barcode. If you are setting this up on your phone, go to Enter a provided key.

Step 12: Enter your email-id alongside the key retrieved (step 9) from Google. Make sure Time-based is selected.

Step 13: Tap on Add.

Step 14: Copy the six-digit code displayed there.

Step 15: Go back to Google Settings, and tap on Next.

Step 16: Enter the six-digit code you copied and tap on Verify.

Step 17: Press Done to finish linking the Authenticator app to your Google account.

Your account would be added. As the codes change quite frequently (Time-based), no need to memorize the codes. Just head over to the add and copy the codes when needed.

Revoke Trusted Device

Losing a device that has access — your laptop for example — to all your login credentials is a nightmare. Not only is the perpetrator getting your valuable possession, but they can also access all your important emails and social media accounts.

Most of us use autofill to simplify the process of signing in. Google’s Two-Step Verification does require an additional step, but it only requires the password in case of trusted devices — devices, which have been used to log in successfully in the past. So, a trusted device with the auto sign-in turned on is a weapon of destruction in the wrong hands. Thankfully, Google has thought about this unfortunate scenario as well. In case your laptop gets stolen, you can head over to settings and revoke the permission for trusted devices.

Step 1: Go to Settings and tap on Google.

Step 2: Tap on Manage your Google account.

Step 3: Go to Menu.

Step 4: Tap on Security.

Step 5: Locate and tap on Two-Step Verification.

Step 6: Enter your password to access Two-Step Verification settings.

Step 7: Scroll down and tap on Revoke all under Devices you trust.

Change Phone Number

If Google Prompts or the Authenticator app isn’t your cup of tea, Google lets you go back to the good old days of text/call-based verification. Simply add the number of your choice, and Google will send a text or make a call with the verification code. Enter the code and the number will be linked with your Google account. If you’ve recently changed your number, you’ll have to link the new number with your Google account to continue enjoying the benefits of Two-Step Verification.

Step 1: Go to Settings and tap on Google.

Step 2: Tap on Manage your Google account.

Step 3: Go to Menu.

Step 4: Tap on Security.

Step 5: Locate and tap on Two-Step Verification.

Step 6: Tap on the little pencil icon (Edit) on the right side of your phone number.

Step 7: Tap on Change phone.

Step 8: Add the new number and tap on Next.

Step 9: Enter the verification code to complete the process.

Similarly, you could also delete your phone verification process by tapping on Delete phone.

How To Add Videos To Google Slides

When you’re creating a professional-looking slideshow, you may want to add a video to it. A well-placed video provides a good “break” in the presentation, mixing things up and holding your audience’s attention.

Of course, you don’t want to pause the slideshow and hunt down your video mid-presentation! If you’re using Google Slides, you can easily set up a video to play within the slide itself, saving you from having to stop the show. You can even set it to automatically play when you reach the slide it’s on, as well as tweaking when to start and stop in the video.

Inserting a YouTube Video

If you want to add a YouTube video to your presentation, most of the work is already done for you! All you need to do is insert it into the slide and tweak it to your liking.

In the “Search” tab you can search YouTube for a video. This is perfect if you have ideas on what kind of video you want for your presentation.

Inserting Your Own Video

If you have a video of your own that you want to share, there are two ways to add it. The first is to upload it to YouTube and perform the steps above. If you’d rather not do that, the second method is to upload it and let Google Slides know where the video is.

Setting the Video Up

A bar will appear on the right. Here you can set a variety of options for your video.

The first option sets a start and end time. If you don’t want to play the entire video, set the times you’d like to play from and to. This is particularly helpful if you want to focus on a specific part of the video and don’t want to hunt for it mid-presentation.

Once you’re finished, play the slideshow and check to be sure everything works properly before going to your presentation.

Smarter Slides

A video is a great addition to any professional slideshow. Now you know how to add one into a Google Slide, whether it’s already uploaded on YouTube or on your computer waiting to be uploaded. You also know how to customise it to your needs to make sure the presentation plays out as you want it to.

How important are videos to you when making a slideshow? Do you have any tips on making a great presentation? Let us know below!

Bu Administrators Add Two Wellness Days To This Semester’s Calendar

BU Administrators Add Two Wellness Days to This Semester’s Calendar

While vegging out and staying off Zoom are two viable options for the upcoming wellness days, the BU Wellbeing Project is planning in-person activities to encourage casual social interactions as well as self-directed wellness activities.

BU Administrators Add Two Wellness Days to This Semester’s Calendar No classes, no homework, and no exams allowed

Add spring break to the growing list of things that have been upended by the coronavirus pandemic. The weeklong March vacation was canceled with the aim of reducing the University community’s risk of COVID-19 exposure. Administrators had worried that having students, faculty, and staff travel could lead to a surge of cases on campus.

But going through the semester without a chance to rest and recharge wasn’t a viable solution, either. In a letter sent on January 13 to students and faculty, Jean Morrison, University provost and chief academic officer, announced that BU has added two wellness days to the spring academic calendar. No classes, no exams, and no homework on those days. In other words, everyone should take the time for a mental health break.

The two wellness days are scheduled for Thursday, March 18, 2023, and Wednesday, March 31, 2023, planned to align with the Presidents Day and Patriots Day holidays, so there is a break in the academic calendar every four to six weeks throughout the semester. 

Sue Kennedy, interim associate provost for undergraduate affairs, whose team helped to coordinate the days, says that breaks from the intensity of the semester are important. “We thought that given what a unique situation this academic year is,” she says, “it is important that students and faculty have periods of respite.” 

BU is not alone in instituting wellness days. Harvard, Penn State, and Duke are among other Universities that have decided to add wellness days to their spring calendar as well. 

Back in November, Student Government’s Mental Health Committee (MHC) proposed the idea for four wellness days. Kennedy says the BU administration considered the request and that Kenneth Elmore (Wheelock’87), associate provost and dean of students, was in contact with student leaders to coordinate a plan.

Morrison’s letter also stated that graduate schools and clinical programs with their own calendars (the School of Law, the School of Social Work, and the Medical Campus schools) have the option of choosing two different days that work better for their calendars. The wellness days do not apply to online-only courses that run for seven weeks. 

“I understand that this calendar adjustment will require some faculty to adjust syllabi and potentially remove some planned content from their courses,” Morrison wrote, before asking for faculty to refrain from adding on work as a makeup. “I hope that we can all embrace these Wellness Days as opportunities to recharge.”

Evan Teplensky (CAS’23), a College of Arts & Sciences Student Government senator, was involved with the planning and echoes that hope, saying that he worries that professors will still quietly assign work and tests for the day following a wellness day, forcing students to use their time off as study time. There have been reports about this on the BU Reddit page. Teplensky urges students to report these instances to their department chair or dean if they find this happening. “It’s important that we really get these days off, these days away from Zoom,” he says.

MHC cochair Savannah Majarwitz (CAS’22) cites a School of Public Health study last September that found that the pandemic has caused the depression rate to triple among US adults, and that even students and faculty who haven’t been diagnosed with depression still need a much-deserved mental health break.

While vegging out and staying off Zoom are two viable options for these days, the BU Wellbeing Project is planning in-person activities to encourage casual social interactions, as well as self-directed wellness activities. BU Today will provide more details on these events in March. 

“We hope that people take the day, go for a walk on the Esplanade, explore Boston safely, and still remember to mask and social distance,” Kennedy says. “Unplug for the day.”
