- Product
- OneDrive and Samsung Gallery
- Device & OS
- Samsung Android
- Scenario
- Attempting to link or sync Samsung Gallery photos with a Microsoft OneDrive account.
- Observed behavior
- An error message appears indicating the Microsoft account is already connected to another Samsung account, preventing the synchronization. The required 'Apps and Services' or 'Linked accounts' menu options to resolve this are missing or difficult to locate on newer devices like the Galaxy S24 Ultra.
Ensure you have the login credentials for both your Microsoft account and your Samsung account, and verify that your Samsung device is updated to the latest One UI version.
Unlink the Microsoft Account from Samsung Settings
Remove the existing OneDrive or Microsoft connection directly from your Samsung account's connected services menu.
Because menu layouts change frequently with Samsung system updates, the exact location of the linked accounts option can vary. This method applies to standard One UI interfaces.
Navigate to the Settings app on your Samsung device and tap on your Samsung account profile at the top of the screen.
Scroll through the account menu and select 'Linked accounts' or 'Connected services'.
Find the Microsoft or OneDrive entry in the list, tap it, and select the option to Unlink or Disconnect.

Revoke Samsung Permissions from Your Microsoft Account
If the unlink option is missing on your phone, you can remove Samsung's access directly from your Microsoft account online.

Frequently Asked Questions
Why does it say my Microsoft account is already connected?
This error occurs if your Microsoft account was previously linked to an older Samsung device, a different Samsung account, or if a previous sync session was improperly terminated. The accounts must be completely unlinked before a new connection can be established.
Where can I find the 'Linked accounts' menu on a Galaxy S24 Ultra?
Depending on your One UI version, it is typically located by tapping your Samsung account name at the very top of the Settings menu, then tapping 'Linked accounts'. If it is missing, search for 'Linked accounts' in the Settings search bar.
Can I use a different cloud service if OneDrive refuses to connect?
Yes. If the connection issue persists and cannot be resolved, you can use alternative photo backup services like Dropbox, Google Photos, or WPS Cloud for documents, which do not rely on Samsung account linking.
