Clear App Cache and Reinstall Microsoft 365 Mobile

Resetting the app's cache or performing a fresh installation can often resolve authentication and connection glitches with third-party cloud services like Box.

Open your Android device's Settings, navigate to Apps, select Microsoft 365, and tap on Storage. Tap 'Clear Cache' and then 'Clear Data' to reset the app locally.

Frequently Asked Questions

Why does my Box connection keep disappearing in Microsoft 365 Mobile?

This typically occurs due to an authentication token expiring unexpectedly or a synchronization bug between Microsoft's servers and the Box API. Clearing the app cache or updating to the latest version can sometimes refresh the token and restore access.

Can I access Box files offline if the connection drops?

No, if the cloud storage connection is lost in the app, you will not be able to browse or open Box files unless they were previously downloaded and explicitly saved to your device's local storage.

Is there a limit to how many cloud storage accounts I can add to Microsoft 365?

While you can add multiple third-party cloud accounts like Box, Dropbox, or Egnyte, managing several connections can sometimes lead to caching conflicts. Try keeping only your primary cloud storage connected to see if connection stability improves.
