Unlike the desktop version of Outlook, the mobile app is standalone and restricted in terms of customization. There are some methods you can use to troubleshoot the issues. Read further to learn about the fixes.

To Fix this, you can start with the most general troubleshooting methods i.e., restarting your mobile. Turn off your mobile by holding down the power button. Wait for a few seconds and turn it on again by pressing the power button.

Clear Cache and Data

Caches are temporary files, such as images, logos, etc., stored on your device. This can accumulate over time and cause numerous conflicts. You should clear the cache to avoid any problems. You can clear Outlook’s cache and data from the settings in Android. However, such features are unavailable on iOS. Instead, you can offload the app.

On Android 

1. Open Settings > Apps.

Note: Clearing data removes all credentials and signs you out from the app. After clearing the data, you should login with your credentials.
