How to Permanently Unlink OneDrive from a Samsung Phone

Product: OneDrive
Device & OS: Android
Scenario: Preparing a Samsung phone for another user or stopping automatic OneDrive logins linked to a Samsung account.
Observed behavior: OneDrive automatically signs in to an old Microsoft account because it remains linked to the device's Samsung account and its connected services.

Before you start

Before proceeding, ensure you have your Microsoft and Samsung account login credentials available in case you need to verify changes, and back up any locally stored files that haven't fully synced to the cloud.

Solution 1Recommended

Remove Microsoft Account from Samsung Connected Services

The most direct method to unlink OneDrive is to remove your Microsoft account from your Samsung account's connected services within the phone's settings.

Open Samsung Settings

Unlock your Samsung phone, open the Settings app, and tap on 'Accounts and backup', or tap directly on your Samsung Account profile name at the top of the menu.

Navigate to Apps & Services

Select your Samsung Account, then find and tap on 'Apps & Services' (sometimes labeled as 'Linked accounts' depending on your specific Android version).

Access Connected Services

Tap on 'Connected Services' to view all the third-party applications and accounts that are currently linked to your Samsung account.

Remove Microsoft Account

Locate 'Microsoft' in the list of connected services, tap on it, and choose 'Disconnect' or 'Unlink' to sever the connection between Samsung and OneDrive.

Success Check: Once removed, OneDrive will no longer be able to use Samsung's system credentials to log in automatically.

Solution 2

Revoke Samsung Data-Sharing Permissions via Microsoft

If you don't have access to the phone's settings, you can revoke Samsung's access directly from your Microsoft account's security page online.

Solution 3

Clear OneDrive App Cache and Verify

If the old account still appears in the OneDrive app after unlinking the services, clearing the app cache will remove lingering login tokens.

Frequently Asked Questions

Will unlinking OneDrive delete my files from my Microsoft account?

No, unlinking OneDrive from your Samsung account only severs the connection between the devices. Your files remain safely stored in your Microsoft cloud and can be accessed via OneDrive.com.

Why does my old OneDrive account keep signing in automatically on my Samsung phone?

This happens because your Microsoft account is linked to your Samsung account under 'Connected Services'. As long as this link exists, Samsung's system will automatically authenticate your OneDrive app using those saved credentials.

Can I link a different OneDrive account to my Samsung phone after unlinking the old one?

Yes. Once you have permanently removed the old Microsoft account from Samsung's Connected Services and cleared the app cache, you can open OneDrive and sign in with a new Microsoft account.

Does clearing the OneDrive app cache delete my local files?

Clearing the app cache and data will remove login credentials and offline-synced files from within the app, but it does not delete your original files in the cloud or independent local files saved outside the app's folder.
