It may happen that the default mail application of Windows 10 no longer works. There are then a number of things you can do to fix the problem – whatever the problem is.
It can always help to restart your computer once in a while. That’s a general solution to a lot of problems, so try that first. If that doesn’t work, check if there is an update available for the Mail app on Windows 10. You can arrange that via the Microsoft Store. Open the menu via the three dots at the top right and go to Downloads and uploads† Find the Mail app and click the download icon on the right.
A third option is to reset the app. Open the power menu of Start (with the right mouse button) and press Apps & Features† Find the Mail and Calendar app and press Advanced settings† In the next window, scroll to Reset and press the corresponding button. After that, the problems might disappear.
Mail app still not working, then what?
The Mail app may still not work. You can then do a few more things. For example, you can deny access to your location. You arrange that through the same Advanced menu as discussed above. You will see the option immediately after opening the page. Another thing that might help, while you’re there, is to allow access to your calendar. In either case, restart the computer.
Mail app still not working? Okay, then it might help to check the sync settings. Within the Mail app, go to the Settings and accounts† Select your account and choose Options for syncing content† Move the slider once from right to left and restart your PC. Now do this again, but throw that button to the left again. Restart your computer again.
It may also help to perform an SFC Scan. With this scan you check whether your PC is affected by corrupted files. You can read exactly how to do that in this article about Windows 10 System File Checker.
Finally, it can help to grant the Mail app access through Microsoft Defender. You do that as follows:
- Go to Settings and to Update and Security
- Go to Windows Security and Firewall and Network Security
- Click now Allow an app through the firewall
- Click on the top right Change settings
- Search Mail and Calendar on and put check marks under private person and Public
- click on OK and check if your mail works again
If this doesn’t work either, you may have a third-party antivirus program that is blocking it. Check the antivirus program you are using to see if it is possible to make exceptions for specific programs. Exactly how this should be done differs per provider. Usually the options for this are under headings like ‘firewall’ or ‘network protection’. If you have any questions, please contact the program’s customer service.
