Reset Mail and Calendar app on Windows 10

Windows 10 includes the Mail app as one of its default built-in apps, and it’s a really good app if you’re looking for a simple email client. The app comes with all the basic features you need, including support for Outlook, Exchange, Gmail, Yahoo, iCloud, POP and IMAP accounts.

However, there will be times when you may come across some issues, such as emails not syncing, problems opening the app, adding new email accounts, and certain settings not working. While the problem usually can be traced to a misconfiguration of an account, it could also be an issue with the Mail app itself.

If you’re having syncing and other issues with the built-in Mail app, you could use PowerShell to uninstall and reinstall the email app using the Store, but this could be a tedious process for everyday users. Thankfully, Windows 10 now includes a reset option to fix any issues with the app without needing to reinstall them.

In this guide, you’ll learn the easy steps to reset the Mail app on Windows 10 to fix any issues.
