Some Mac users are encountering the ‘You’re already syncing this account‘ error in OneDrive and OneDrive Business whenever they try to add new work or school account or whenever they try to synchronize the files between OneDrive Online and the OneDrive for Mac app.
In most cases, the ‘You’re already syncing this account‘ error will appear due to badly cached data stored inside the OneDrive Cached Credential folder. In order to fix the issue, you can use the KeyChain utility to find and clear the OneDrive Cached Credential data.
But if you want to take the focused approach, the most efficient way of resolving this issue is to use access the Group Container folders and deleting the two folders belonging to OneDrive (UBF8T346G9.OneDriveSyncClientSuite.plist and UBF8T346G9.OfficeOneDriveSyncIntegration.plist).
However, if you don’t want to get your hands dirty at all, you can simply access the Resource folder belonging to Onedrive and run the ResetOneDriveApp.command or ResetOneDriveAppStandalone.command (depending on your OneDrive version) in order to reset the entire applications.
Method 1: Clearing the OneDrive Cached Credential
As it turns out, this particular issue can occur due to badly cached data stored inside the OneDrive Cached Credential folder. If this scenario is applicable, you should start by the less intrusive approach – in this case, this is clearing the OneDrive Cached Credential file.
Several affected users have reported that they managed to fix the issue by opening the KeyChan Access utility and using it to find and delete the OneDrive Cached Credential.
Here’s a quick guide on how to do this:
- Ensure that OneDrive and every associated instance is closed.
- Click on the Spotlight icon (top-right corner of the screen) and search for ‘Keychain Access‘ and hit Return. Next, from the list of results, click on Keychain Access and wait for the utility to open.
- Once the KeyChain Access utility is loaded, use the search function in the top-right section of the screen to search for ‘OneDrive‘ and press on Return.

Method 2: Deleting two syncing files
As it turns out, there are two files called UBF8T346G9.OneDriveSyncClientSuite.plist and UBF8T346G9.OfficeOneDriveSyncIntegration.plist that are located in /Users/[username]/Library/Group Containers/ which are often signalled by users as being responsible for the apparition of the ‘You’re already syncing this account‘ error.
The first file (ClientSuite) contains all the info regarding the accounts that you’re currently loge into, while the second one (Integration) contains log and file data about every SharePoint folder that you’ve ever connected to.
Since OneDrive has the ability to regenerate the files without any other inconveniences, you should be able to fix the issue by using the Keychain Access utility to find and delete the two files responsible for the error.
Here is a step by step guide that will allow you to delete the two syncing files that are most likely causing the ‘You’re already syncing this account‘ error:
- Ensure that OneDrive and every other associated instance is closed.
- Click on your Finder icon (bottom-left corner of the screen).

- Restart OneDrive and see if the issue is now resolved.

Method 3: Resetting OneDrive via Resources folder
If the above methods didn’t allow you to fix the issue, it’s most likely due to the fact that some temporary files are interfering with Onedrive’s ability to sync files in real-time. One way to fix this problem is to simply run the ResetOneDriveApp.command in order to refresh every component automatically.
If this scenario is applicable, you should be able to fix the issue swiftly and OneDrive should syncronize normally the next time you start it.
Here’s a quick guide on Resetting OneDrive via the Resources folder:
- Ensure that OneDrive and any associated instance is closed. The quickest way to do this is by going to the cloud icon in the top tray and select Settings > Quit OneDrive.
- Next, click on the Finder icon (bottom-left section) and wait for the application to load.
- Inside the Finder app, use the search function (top-right section) to search for ‘OneDrive’ and press Enter.
Note: Ensure the search covers This mac, not Recents, otherwise you will not be able to find Ondedrive.
- Next, from the list of results, locate your OneDrive application, right-click on it and choose Show Package Contents from the newly appeared context menu.
- Inside the show package contents folder, click on Contents and then open up the Resources folder.
- Once you’re inside the Resources folder, double-click on the ResetOneDriveApp.command file and wait for the command to be processed in the terminal.
Note: If you’re using the standalone app, run the ResetOneDriveAppStandalone.command file instead.
- After the operation is complete, restart OneDrive, sign in with your user credentials once again and see if the problem is now fixed.
