Windows 10 Mail app is an email system that was created by Microsoft as the primary way of sending and receiving emails. Windows Mail app has been included in the Windows operating system since the development of Windows Vista.

One of the biggest problems users report about the mail app is that it just won’t open, the mail app basically fails to launch. This is a little different than when your Windows 10 Photo app won’t open, which has a different resolution.

But for the mail app, we’ve found a great remedy for this and we have looked at some of the easiest and quickest fixes that you can try to get your mail app to open so you can get back to checking your emails.

Windows 10 Mail app won’t open – The fix

If you’re finding the Windows 10 mail app not opening on your device, then the first thing you’ll want to check is your privacy settings. Make sure they’re not stopping your Mail app from opening by being too restrictive.

You’ll also want to make sure that the app is updated and run through your other settings too. Here’s how to do that in a little more depth.

Check your privacy settings don’t deny access to Windows 10 mail opening


One of the most simple ways to fix the issue with the Windows 10 mail app failing to boot is to do with privacy settings.

Windows 10 is one of the biggest and most used operating systems in the world, it collects data from you constantly, but due to data and privacy laws, there are a plethora of privacy settings to go along with the operating system that helps to protect the user.

You can basically deny access to every feature of the operating system with these settings.

As such, it is important for you to check that your privacy settings are allowing access to your mail app because without permissions being granted to your calendar specifically the app will not open.

To do this follow the steps laid out here for you:

  1. Go to the ‘Start’ menu.
  2. Open ‘Settings App.’
  3. Scroll to the section that says ‘Privacy.’
  4. On the left-hand side you will see the ‘Calendar’ option.
  5. Select the ‘Calendar.’
  6. Check the section that says ‘Let apps access my calendars.’
  7. Under ‘Choose apps that can access calendar’ select Mail.
  8. Ensure there is a check next to this option.
  9. Try your Windows 10 mail app again to see if this has resolved the issue.

Update your mail app

When your mail app won’t load your next fix is pretty simple, update. A lot of users put off updates because you don’t want to wait for them to install while you need your computer, which is usually the time you find out you need to update.
