Question details

The user needs to stop the OneDrive iOS app from prompting for a nonexistent work account (Entra ID) that shares the same email address as their personal Microsoft account.

How to Separate a Personal Microsoft Account from an Old Entra ID Account on OneDrive iOS

Product: OneDrive for iOS
Device & OS: iOS
Scenario: Signing into the OneDrive app on iOS after a custom domain was removed from a development tenant.
Observed behavior: OneDrive for iOS continually prompts for or attempts to use the nonexistent former business account instead of the active personal Microsoft account.

Before you start

Ensure you have your current personal Microsoft account credentials ready and confirm that all recent local changes in your OneDrive app have been synced to the cloud.

Solution 1Recommended

Uninstall and Reinstall OneDrive for iOS

Clearing the app cache by completely reinstalling it can remove lingering work account credentials stored locally on your device.

Because iOS apps often cache authentication tokens, the simplest way to clear a stuck Entra ID login prompt is a fresh installation.

Remove the OneDrive app

Press and hold the OneDrive icon on your iOS home screen, tap 'Remove App', and select 'Delete App' to confirm.

Reinstall from the App Store

Open the Apple App Store, search for 'Microsoft OneDrive', and download the application again.

Sign in with your personal account

Open the newly installed OneDrive app and sign in using your personal Microsoft account credentials.

Uninstall and Reinstall OneDrive for iOS

Data Safety: Deleting the OneDrive app does not delete your cloud files. Your data will reappear once you sign back in successfully.

Solution 2

Add a New Alias to Your Personal Microsoft Account

Creating a new login alias forces the system to recognize a unique identifier, bypassing the conflict with the old Entra ID email address.

Solution 3

Contact Microsoft Support

If the nonexistent work account prompt persists, you may need backend assistance from Microsoft to fully unlink the Entra ID.

Frequently Asked Questions

Why is OneDrive for iOS asking for an old work account that no longer exists?

This usually happens because the OneDrive iOS app caches old authentication tokens. Even after a custom domain is removed from an Entra ID (formerly Azure AD) tenant, the local app may still attempt to authenticate using the old cached credentials associated with that specific email address.

What is a Microsoft account alias?

An alias is an additional email address or phone number associated with your Microsoft account. It shares the same inbox, contact list, and account settings as your primary email, allowing you to sign in without triggering conflicts with identical emails previously used for business accounts.

Will reinstalling the OneDrive app on my iPhone delete my files?

No, reinstalling the OneDrive app will not delete any files stored in the cloud. However, any files marked for offline access will be removed from local storage and will need to be downloaded again once you reinstall and sign back into the app.
