Question details

Users encounter an AADSTS90072 error stating their personal live.com account does not exist in an organization's tenant when attempting to open a Word file from OneDrive.

Product: Microsoft Word for Android, OneDrive
Device & OS: Android
Scenario: Opening a OneDrive file in Word for Android as a personal or home user.
Observed behavior: Microsoft Authenticator triggers and blocks access with error AADSTS90072, claiming the account doesn't belong to a foreign enterprise tenant.

Before you start

Ensure you have your personal Microsoft account credentials (email and password) ready, as you will need to sign back in after clearing the cached session data.

Solution 1Recommended

Remove Cached Work Accounts and Clear App Data

This removes lingering organizational accounts on your Android device that conflict with your personal Microsoft account during authentication.

The AADSTS90072 error usually occurs because your Android device or Microsoft Authenticator app has cached a previous organizational session. When you try to open a file, the app mistakenly tries to authenticate your personal account against that organization's tenant directory.

Sign out of all Microsoft apps

Open Word, Microsoft 365, OneDrive, and the Microsoft Authenticator app on your Android device and manually sign out of all currently logged-in accounts.

Remove the account from Android settings

Go to your Android device Settings > Accounts (or Users & Accounts). Locate any unwanted work or school accounts, tap on them, and select 'Remove account'.

Clear application caches

Navigate to Settings > Apps > Manage Apps. Select Word, OneDrive, and Authenticator individually. Tap on 'Storage' and select 'Clear Cache' and 'Clear Data' for each.

Restart and sign in

Restart your Android device. Open the Word app and sign in using only your correct personal Microsoft account credentials.

Check Default Accounts: Clearing the app data forces the application to prompt you for a fresh login, successfully bypassing the old tenant cache.

Solution 2

Reinstall Microsoft Apps and Verify Link Sharing

If clearing the cache does not resolve the issue, a clean installation ensures no residual enterprise data forces the AADSTS90072 error.

Frequently Asked Questions

What does error AADSTS90072 mean?

Error AADSTS90072 indicates that the Microsoft account you are using does not exist in the specific organization's tenant directory (Azure Active Directory) that is requesting authentication. This often happens when a personal account is mistakenly routed to a work or school login portal.

Why is Microsoft Authenticator triggering for a personal file?

Your Android device may have a cached token from a previous work or school account. When you open a Microsoft app, it defaults to the cached organizational profile, which forces the Authenticator app to prompt for enterprise verification.

Can I use OneDrive without Microsoft Authenticator?

Yes, for personal accounts, you can usually sign in with just a password or a standard email code. You can remove Microsoft Authenticator from your personal account's security settings via the Microsoft account dashboard online.

Will clearing the app data delete my saved Word files?

No, clearing the app data or cache only removes temporary files and session settings. It will force you to sign in again, but files saved securely to OneDrive or your device's local documents folder will remain unaffected.
