Question details

The user is unable to edit Office documents stored in a personal OneDrive account on their mobile device and is continuously prompted to purchase a business subscription despite owning a Microsoft 365 Family plan.

Product: Microsoft 365 / OneDrive
Device & OS: Phone (Android/iOS)
Scenario: Attempting to open and edit personal documents using the mobile Office or OneDrive app.
Observed behavior: Files are forced into read-only mode, and the application displays prompts requesting a business subscription, ignoring the active Microsoft 365 Family credentials.

Before you start

Ensure you know the email address and password for your personal Microsoft 365 Family account, as you will need to sign back into the application after clearing the local cache.

Clear App Cache and Remove Conflicting Work Accounts

Sign out of conflicting accounts and clear the OneDrive app data to force the application to recognize your personal Microsoft 365 Family subscription.

When you use a mobile device for both personal and professional tasks, Office apps and OneDrive can cache credentials from a work or school account. This cached data often overrides your personal Microsoft 365 Family plan permissions, causing the app to lock files as read-only and demand a business license.

Sign out of work or school accounts

Open the OneDrive app on your phone, go to the 'Me' or 'Settings' tab, and sign out of any connected work or school accounts.

Clear the OneDrive app cache and data

Navigate to your phone's general Settings, select 'Apps' or 'App Management', find 'OneDrive', and tap on 'Storage'. Select both 'Clear Cache' and 'Clear Data'.

Remove work accounts from device settings

In your phone's main Settings, go to 'Accounts' or 'Users & Accounts'. Locate any work or school Microsoft accounts and remove them from the device.

Sign in with your personal account

Reopen the OneDrive app and sign in using only your personal Microsoft account associated with your Microsoft 365 Family subscription. Try opening a file to verify you have editing rights.

Data Safety Note: Clearing the app cache and data will not delete any files stored in the OneDrive cloud. However, any files you have made available for offline access will need to be downloaded again.

Frequently Asked Questions

Why does Microsoft 365 Family say I need a business subscription?

This happens when cached credentials from a work or school account override your personal account settings. The mobile app detects the enterprise token and incorrectly applies business licensing rules to your personal files.

Will clearing my OneDrive app data delete my photos or documents?

No, clearing the app data only resets local application settings and removes locally cached or offline files. Your actual documents and photos remain safely stored in the cloud and will reappear once you sign back in.

Can I have both work and personal OneDrive accounts on the same phone?

Yes, but if you experience read-only errors, you should completely sign out of both accounts, clear the app data, and sign in with your personal account first before re-adding your work account.

Are there other reasons why my OneDrive files might be read-only?

Aside from account conflicts, files can open as read-only if they are locked by another user, if your Microsoft 365 subscription has expired, or if the file format is unsupported or restricted by password protection.
