The Windows 10 Mail app is probably the most useful of the preinstalled default apps on the operating system. It allows you to quickly and easily setup a variety of different email accounts and manage them all from a safe user-friendly location. Although the Mail app usually escapes update bugs, this time around it wasn’t so lucky, with error 0x8007139f making a Mail app appearance.

Anyone familiar with Windows knows Microsoft has a terrible track record when it comes to Windows 10 updates. No major update or even minor update so far has been without some kind of issue, the Windows 10 April update holds strong to this tradition. Although most update issues and errors can be fixed easily there is one major problem identified in the April update that everyone should be aware of and is linked to a previous Windows 10 automatic update error, which caused Error 0x80070002.

When manually updating to Windows 10 version 1803 from an older version stuck with cumulative update error 0x80070002, Windows becomes corrupted beyond repair and requires a fresh install. Although this is in no way related to the mail app issue, it is something I think everyone should be aware of, especially since most people have more than one Windows 10 device in their household. So if you have a computer that has this error message, make sure you make a backup of your system before installing the April Update.

Note: There are many “possible” fixes for cumulative update error 0x80070002, however, none of them are guaranteed to work. The magic fix was thought to be manually updating to 1803 using the official Microsoft Manual Update Tools.

Getting back on topic, the issue with the Windows Mail app isn’t a serious error and can be fixed by simply toggling a few newly added/rearranged settings in the Privacy menu. For anyone accustomed to using Windows 10 and its fondness for tracking, there is a good chance you have accidentally disabled a setting the mail app needs to function.

How to Fix Windows 10 Mail App Error 0x8007139f.

To begin open the Settings menu go to Privacy, then select Email from the list of options in the left-hand pane. Next, enable Allow Apps to Access Your Email and make sure the Mail and Calendar option below is also enabled. If these options are already enabled when you enter the menu, disable them, Restart your computer, then re-enable them. After your computer restarts, the Windows Mail app will allow you to use the app without error 0x8007139f.

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.

5 Ways To Fix Mail App Missing On Iphone

Don’t get shocked if the Mail App is missing from your iPhone. You’re not alone, my friend! Many users have reported this issue on iOS 16. So, whether the app is accidentally deleted or simply disappeared, you can get it back quickly. So, let’s learn how to restore the Mail app on iPhone.

Why Mail app disappeared from iPhone?

If your iPhone Mail App is missing, you can’t access your mail accounts and get new emails. So, before you start troubleshooting the problem, find the root of the cause.

The most probable reason is that you might have removed the app icon from Home Screen while customizing or have deleted it. Besides, the app may be restricted. If not, your iPhone maybe got some bugs, wrong settings, system crashes, update failures, etc. But don’t worry!

How to restore Mail app on iPhone

No doubt, the Mail app is essential in everyone’s daily life. I will share 5 tips to get the Mail app back on your iPhone.

1. Add Mail app to Home Screen

At times, the app is installed on your iPhone but not visible.

I lost the Mail icon when I tried to create an empty Home Screen on my iPhone. So, I thought of adding it to the dock for quick accessibility.

Swipe left until you reach the App Library.

Now, search for Mail.

The Mail app icon will be added to your Home Screen. If you don’t see the option, it is hidden in a Home Screen folder. So, hold and drag the app icon back to your Home Screen.

Also, you may relocate the icon according to your preference. Just press any empty space on your Home Screen until the icons jiggle, and drag the Mail icon.

Sometimes we accidentally delete apps or use the Offload Unused Apps feature on iPhone. This can be the reason for the missing Mail app icon. So, to restore it, just reinstall the app from the App Store.

2. Reinstall mail app

Open App Store → search Mail.

Now, locate the app and tap the cloud icon to re-download it.

Reinstalling the app may not always fix the issue. If you have opted for blocking inappropriate content, the Mail app can go missing from your iPhone. 

3. Disable Mail in Screen Time

Launch Settings → tap Screen Time. 

Choose Always Allowed.

Now, check if the app icon is restored on the Home Screen.

Sometimes different settings overlap and cause bugs that may result in missing app icons. Therefore, I suggest resetting your iPhone to get back to the default. You may opt for a factory reset or only reset the settings, which will not delete your files and media.

4. Reset All Settings on iPhone

Go to Settings → General.

Scroll down and tap Transfer or Reset iPhone.

Enter your passcode and confirm your choice by selecting Reset All Settings.

If no methods work for you, the only way open is to contact Apple Support. They will analyze your problem and suggest the most suitable solution.


Q. What to do if my accounts do not show up in the Mail app?

First, go to Settings → Mail → Accounts. Now verify if the Mail is enabled for all your email accounts. Then restart your iPhone. If the issue persists, remove the email account from your iPhone and add it again.

Q. I can’t see new emails; how to fix it?

If you do not receive new emails, check if the Push feature is enabled. Then, navigate to Settings → Mail → Accounts → Fetch New Data and toggle on Push. Remember, it will only work when you are using Wi-Fi and have disabled Low Power Mode.

Q. How to fix Apple Mail all inboxes disappeared issue?

All inboxes folder allows you to access emails from all synced accounts. If it’s missing, go to the Mail app and tap the top left corner to get Mailboxes. Now, tap Edit → All Inboxes → Done.

So, that’s all for today, folks!
