Frequently Asked Questions

Why are my personal files showing up in my business account?

This happens when multiple accounts (personal and business) are signed into the same Microsoft 365 mobile app simultaneously. The app caches and blends the recent files view, causing personal files to appear alongside business documents.

Will resetting the Microsoft 365 app delete my files?

No, resetting the app only clears local app data, cache, and sign-in information. Your personal and business files remain safely stored in OneDrive or your device's local storage.

How do I remove a personal account from the Microsoft 365 app entirely?

Tap your profile icon in the app, select your personal account, navigate to the account Settings, and choose 'Sign Out'. This removes the account's access and clears its synced files from your recent list.
