How to Remove Old Microsoft Accounts from Office Apps on Android

Product: Microsoft Office (PowerPoint, Office, OneNote)
Device & OS: Android (Samsung Galaxy Note 9)
Scenario: Attempting to completely sign out and remove old Microsoft accounts from the device to clean up the app or switch to a new user profile.
Observed behavior: Old Microsoft accounts continue to appear in PowerPoint, Office, and OneNote even after signing out, removing the accounts from Android settings, and clearing app data.

Before you start

Ensure you have the login credentials for your current or preferred Microsoft account, as you will need to sign back in after clearing the app data.

Solution 1Recommended

Clear Storage Data and Cache for All Microsoft Apps

Resetting the storage and cache directly from the Android system settings forces the Office app to clear out cached account remnants.

Sometimes, simply signing out within the app does not clear the cached credentials stored by the Android system. You must clear both the data and cache for every affected Microsoft app to prevent the old account from automatically syncing back.

Open Android Settings

Navigate to your device's Settings app and select 'Apps' or 'Application Manager' depending on your Android version.

Locate the Office App

Scroll through the list of installed applications and tap on the specific Microsoft app causing the issue, such as 'Office', 'PowerPoint', or 'OneNote'.

Clear Cache and Data

Tap on 'Storage', then select 'Clear cache' followed by 'Clear data'. Confirm any prompts that appear.

Relaunch and Sign In

Reopen the Microsoft app. You should now be prompted to sign in fresh. If the issue persists across multiple apps, repeat these steps for every Microsoft app installed on your device.

Clear Storage Data and Cache for All Microsoft Apps

Repeat for All Microsoft Apps: Because Microsoft apps share single sign-on (SSO) credentials on Android, leaving cached data in even one app (like OneDrive or Outlook) might cause the old account to reappear in PowerPoint or Word.

Solution 2

Remove Connected Accounts via Android System Settings

Remove the account from the device's system-level account manager, particularly checking for hidden 'Work or School' accounts.

Frequently Asked Questions

Why do my old Microsoft accounts keep reappearing after I sign out?

This happens because Microsoft apps on Android share Single Sign-On (SSO) credentials. If the account data is still cached in the Android system or in another Microsoft app (like OneDrive or Outlook), it will automatically push the account back into Office, PowerPoint, or OneNote.

Will clearing my Office app data delete my documents?

No. Clearing app data only removes local app settings, preferences, and login caches. Your actual documents are safe, whether they are saved in your device's local storage or backed up to a cloud service.

How do I unlink an Android device from my Microsoft account?

You can unlink your device by logging into your Microsoft account via a web browser, navigating to the 'Devices' section, locating your Android phone (e.g., Samsung Galaxy Note 9), and selecting 'Remove device' or 'Unlink'.

Can I use Microsoft Office apps on Android without signing in?

You can use Microsoft Office apps to view documents without an account. However, creating new documents or editing existing ones usually requires you to sign in with a free Microsoft account or an active Microsoft 365 subscription.
