Here see how you can use Windows 10 email repair tool to reset the email app for fixing issues such as app not opening, crashing unexpectedly, problems with settings and syncing emails. You can use the instructions in this guide to fix the Calendar app on Windows 10 as well.
Microsoft has bundled in a fantastic universal email app in the latest Windows 10 operating system which you can use to manage all your email accounts from one place. However, like any other app, the Windows 10 email app is not without its issues. Sometimes the email app fails to open, doesn’t sync properly, or could face other issues due to other issues.
Most common issue being faced by Windows 10 users include mails not syncing, the mail app not opening, issues with adding new email accounts, and certain functions not working, among other issues with the app Settings.
There could be any number of reasons behind these performance issues with the email app on Windows 10; it could be that the app has not been configured properly, or changes in settings not applying, or any other reason. But almost all of these issues could be fixed easily by resetting Windows 10 Mail app.
When something goes wrong with default OneDrive and Store apps on Windows 10, you can use a reset command to fix issues with them. However, this is not the case with the universal Mail (and Calendar) app on Windows 10 because there is no reset command to fix these apps. To address issues with the mail app, you need to uninstall the app from computer, and reinstall it again, but that won’t be as straight forward as uninstalling other apps on Windows 10 as the mail app is the universal default app.
In this Windows 10 guide, we are going to show you how to use the PowerShell command-line shell tool to reset the Mail app by uninstall it from computer, and reinstall it again through the store.
How to Uninstall the Windows 10 Mail App
1 – Open Start menu and type Windows PowerShell, right-click on the PowerShell on the search result and select Run as administrator to open it.
2 – In the PowerShell, type the following command and hit enter:
Get-AppxPackage Microsoft.windowscommunicationsapps | Remove-AppxPackage
3 – Wait for the command to execute and restart PC.
This will remove the Windows 10 mail (and calendar apps) from your device. Follow the steps below to reinstall the mail app.
How to Reinstall Windows 10 Mail App
1 – Open the Windows Store.
2 – Type Mail and Calendar in the search bar and click on the app from the search result.
3 – Click the Install button.
4 – Once installed, open the newly installed Windows 10 mail app from the start menu and follow on-screens setup instructions as prompted.
5 – That’s all.
If you are facing issues during the app installation, restart computer and try installing the mail app again. With this method you will have to go through the app configuration settings all over again including adding previous email accounts and settings for each one of them.
You can now start using the Mail app on Windows 10 computer, hopefully this time without app not opening, emails not syncing, or settings not working issues.
There is one more thing you can do to see if that fixes the issues with the mail app. Sometimes the wrongly configured Privacy settings on Windows 10 could also result in issues with the mail app. To fix that, go to Settings > Privacy and make sure under Email or Calendar, the Mail and Calendar option is enabled.
[Update]: Starting from the Windows 10 Creators Update, you can fix the mail app issues from Settings > Apps & features > Mail and Calendar > Advanced options and click the Reset button. This will clear the app data after which you can setup the app again with new settings.
