The Mail app is the default email client in Windows 10. The Mail app was first introduced with Windows 8 and has been improved dramatically in Windows 10. It supports not just Microsoft accounts but other webmail service accounts as well.
If your Mail is not syncing your messages, not opened or showing an error, resetting the app might fix the issue.
Reinstalling the Mail app is the best way out there to clear the Mail app data and fix all its issues. But resetting the Mail app much easier than reinstalling it.

I kept getting a message to say the settings on one my accounts were out of date despite having apparently “fixed” it, and I also had an old notification number stuck on my task bar icon which wouldn’t shift. I was about to attempt to in-install and re-install the app when I found this link. Both problems are now resolved, many thanks.

Jon Thompson says
Brilliant, thank you. If only Microsoft staff had seen this, had me reinstalling Windows and all sorts when a simple reset was all that was needed. I didn’t even lose the emails and accounts.
