The user needs to permanently remove an unused Microsoft account that persistently appears in the account list of the Microsoft 365 app on their Android device.

How to Remove a Microsoft Account from the Android Microsoft 365 App

Product: Microsoft 365 App
Device & OS: Android (Samsung Galaxy S21)
Scenario: Attempting to clean up the 'Add or Switch Accounts' list by removing an old or unused Microsoft account from the device.
Observed behavior: The unused account continues to display in the app's account switching list even after clearing the application cache, reinstalling the app, and verifying standard Android account settings.

Before you start

Ensure you have the login credentials for your primary Microsoft accounts saved, as you will need to sign back in after clearing the application data for your Microsoft apps.

Solution 1Recommended

Clear Data and Reinstall All Microsoft Applications

Because Microsoft accounts share authentication tokens across all installed Microsoft applications, you must clear the data and reinstall all related apps to fully remove the lingering account.

Microsoft uses a centralized authentication service on Android. This means an account logged into apps like Outlook, Teams, Edge, or Skype will automatically populate the account list in your Microsoft 365 app.

To resolve this, you must clear the application data and uninstall all Microsoft apps, not just the Microsoft 365 app.

Remove from Android Settings

Go to your Android Settings > 'Accounts and backup' (or 'Passwords & accounts') > 'Manage accounts', and remove the Microsoft account if it is listed.

Clear Data for All MS Apps

Go to Settings > 'Apps'. Find all installed Microsoft apps (Microsoft 365, Outlook, Teams, Word, Excel, Edge, Skype). For each app, tap 'Storage' and select 'Clear Data' and 'Clear Cache'.

Uninstall All Microsoft Apps

After clearing the data, uninstall all of these Microsoft applications from your device.

Reinstall and Sign In

Open the Google Play Store, reinstall the Microsoft 365 app (and any other necessary apps), and sign in using only the active accounts you need.

Clear Data and Reinstall All Microsoft Applications

Device Differences: On Samsung devices, 'Manage Accounts' is found under 'Accounts and backup'. Ensure you check thoroughly, as lingering accounts in Samsung Cloud or other Samsung features can sometimes interfere.

Solution 2

Remove the Account via Microsoft Authenticator

If you have the Microsoft Authenticator app installed, it acts as a central hub for your credentials. Removing the account directly from Authenticator can resolve the issue without uninstalling other apps.

Frequently Asked Questions

Why does a deleted account still show up in the Microsoft 365 app?

Microsoft applications on Android share a centralized authenticator token and account cache. If the account is still actively logged into another app like Outlook, Teams, or Edge on the same device, it will persist in the Microsoft 365 app's account list.

Can I remove the account without uninstalling all my Microsoft apps?

Sometimes. You can try clearing the cache and data specifically for the Microsoft Authenticator app and the Microsoft 365 app. However, if the account is deeply cached by Android's account manager, a full clear and reinstallation of all related MS apps is often the only permanent fix.

Where do I find the account management settings on a Samsung Galaxy device?

On Samsung Galaxy devices, open your device 'Settings', scroll down and tap on 'Accounts and backup', and then tap on 'Manage accounts'. Here, you can view and remove accounts linked to your device.
