Question details

The user is unable to edit files in the OneDrive mobile app because they have become read-only following changes to work and personal accounts. Attempting to sign in with a non-Microsoft email also results in an error stating no work or school account exists.

Product: OneDrive Mobile App
Device & OS: not provided
Scenario: Accessing and editing cloud documents on a mobile device after modifying account configurations or switching between work and personal Microsoft profiles.
Observed behavior: Files are locked in read-only mode preventing edits, and signing in with a third-party email triggers an account existence error.

Before you start

Before proceeding, ensure that any recent offline edits are saved locally or fully synced to the cloud, as clearing app data will remove temporary unsynced changes.

Solution 1Recommended

Clear OneDrive App Cache and Re-sign In

Use this solution to resolve authentication conflicts and corrupted temporary data that lock files into read-only mode.

When you switch between work and personal accounts, the OneDrive app's cache can occasionally become corrupted or misread your permissions. Clearing the cache forces the app to re-authenticate your credentials and fetch the correct file permissions directly from the server.

Sign out of all accounts

Open the OneDrive mobile app, navigate to Settings, and sign out of both your personal and work accounts.

Clear app cache and data

Go to your mobile device's system settings, find the App Manager (or Apps), select OneDrive, and tap on 'Clear Cache' followed by 'Clear Data' (or 'Clear Storage').

Remove saved accounts

If your device has a system-level account manager, navigate there and remove any saved Microsoft accounts to prevent auto-login conflicts.

Sign in again

Reopen the OneDrive app and sign in using only your personal account first to verify that editing capabilities have been restored.

Confirmed Fix: Users have confirmed that clearing the app cache completely resolves the read-only issue and allows remote editing to work again, even alongside a work account.

Solution 2

Verify Account Alias for Non-Microsoft Emails

Apply this if you are using a third-party email (like Gmail or Yahoo) and encountering errors stating that no account exists.

Frequently Asked Questions

Why do my mobile cloud files suddenly say read-only?

This usually happens due to cached authentication conflicts when switching between personal and work accounts, or if your mobile Office 365 subscription status fails to sync properly.

Will clearing the OneDrive app data delete my cloud files?

No. Clearing the app cache and data only removes temporary files, offline copies, and login data stored locally on your device. Your actual files are safely stored in the cloud.

How do I add an alias to my Microsoft account?

Sign in to account.microsoft.com, go to 'Your info', select 'Edit account info', and choose 'Add email'. You can then create a new Outlook.com address to act as your alias.

Can I use multiple accounts on the same mobile cloud app?

Yes, most cloud apps allow you to add multiple accounts. However, if you experience sync or editing issues, it is best to sign out of all of them, clear the app cache, and sign back in to refresh your permissions.
