How to Fix the OneDrive and Samsung Gallery Account Connection Error
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.
Before you start

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.

Solution 1Recommended

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.

1
Open Settings

Navigate to the Settings app on your Samsung device and tap on your Samsung account profile at the top of the screen.

2
Locate Linked Accounts

Scroll through the account menu and select 'Linked accounts' or 'Connected services'.

3
Disconnect Microsoft

Find the Microsoft or OneDrive entry in the list, tap it, and select the option to Unlink or Disconnect.

Unlink the Microsoft Account from Samsung Settings
Missing Option: If you do not see 'Linked accounts', check under 'Settings > Accounts and backup > Manage accounts' instead.

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.
