Question details

The user wants to remove a specific, automatically added Microsoft account that has been set as the default in the OneNote Android application.

Product: Microsoft OneNote
Device & OS: Android (Galaxy Tab S9+)
Scenario: Managing logged-in accounts and removing an undesired default account within the mobile app.
Observed behavior: OneNote automatically added an account and set it as default, but there is no visible setting in the app to remove only that specific account without affecting others.

Before you start

Before making any changes or clearing app data, ensure that all your recent notes are fully synchronized to the cloud to prevent permanent data loss.

Solution 1Recommended

Clear OneNote App Data and Cache

Since OneNote on Android does not provide an option to remove a single account, clearing the app data will reset the login state, allowing you to sign in with only the correct account.

Android applications often store account credentials in their local data. Clearing this data forces the app to 'forget' the automatically added account.

Open Android Settings

Navigate to your device's home screen or app drawer and open the 'Settings' application.

Navigate to Apps

Scroll down and tap on 'Apps' or 'App Management' to view the list of installed applications.

Find OneNote

Scroll through the list or use the search bar to locate and tap on 'OneNote'.

Clear Storage Data

Tap on 'Storage' or 'Storage & cache', then select 'Clear Data' (or 'Clear Storage') and 'Clear Cache'.

Sign In Again

Reopen the OneNote app and sign in using only the account you wish to use as your default.

Data Deletion Warning: Clearing app data will delete any local, unsynced notes. Always verify your notes are backed up online before proceeding.

Solution 2

Sign Out Completely via the App

If you prefer not to clear app data from system settings, you can attempt to sign out of all accounts directly from the OneNote app interface.

Solution 3

Reinstall OneNote from Google Play

If the unwanted account remains persistent despite clearing data, a clean reinstallation will remove all residual account files.

Frequently Asked Questions

Why can't I remove just one account from OneNote on Android?

Microsoft often binds account credentials at the application or device level for seamless integration across its Office apps. Because of this design, individual account removal isn't always supported, meaning you must reset the app data or sign out entirely to clear the saved credentials.

Will clearing OneNote's app data delete my notebooks?

No, it will not delete notebooks that have been successfully synced to OneDrive. However, any local notes that have not yet been synced to the cloud will be permanently lost when you clear the app data. Always verify your sync status first.

How do I prevent OneNote from automatically adding accounts in the future?

Android devices sometimes pull Microsoft accounts logged into other apps (like Outlook or Edge) or the device's main settings. To prevent this, go to Android Settings > Accounts, and remove the unwanted Microsoft account from the system level before signing into OneNote.
