Locate Microsoft 365

Tap on 'Apps' and scroll down through your installed applications to select 'Microsoft 365'.

Frequently Asked Questions

Why does the Scan feature specifically cause Microsoft 365 to crash?

The Scan feature requires camera permissions and significant RAM. If your phone has low memory or background apps are consuming resources, activating the camera module through the application can trigger an immediate crash.

Will I lose my documents if I uninstall the Microsoft 365 app?

No, uninstalling the app will not delete documents that are successfully saved to your OneDrive cloud storage. However, any locally saved files on your device that haven't been synced might be lost, so back them up first.

How do I know if a background app is conflicting with Microsoft 365?

You can boot your Samsung device into Safe Mode. If Microsoft 365 runs smoothly in Safe Mode, a third-party application running in the background is likely causing the conflict.

Does clearing the cache log me out of my Microsoft account?

Clearing the 'Cache' only removes temporary files and keeps your account logged in. However, tapping 'Clear Data' will reset the application entirely and log you out, requiring you to sign back in.
