Microsoft’s Outlook for Android is perhaps one of the best apps to stay connected with your email accounts, including Outlook, Gmail, Microsoft 365, Exchange, and Yahoo. Also, you can easily manage your calendars and files using a single experience.

It is a nearly perfect mobile app. The only caveat with Outlook is that at some point, you will notice that new emails will take too long to appear in your inbox, or they won’t sync at all.

If you have already tried restarting the app and rebooting the phone, but the Outlook app is still not syncing your emails, calendars, and files, it is possible to reset the app to fix this and many other common problems.

This guide will teach you how to reset the Outlook app when not working on Android.
