☁️ How to disconnect OneDrive on macOS from an extra account that doesn’t exist anymore.

On my work computer I used to have two OneDrive accounts, one Business and one that Microsoft considered “Personal” even though it was used for work files on my work address. Eventually I deleted the extra “personal” account since we were consolidating.

But every time I restarted the MacBook, it would try to connect to both OneDrive accounts for syncing. I could quit the extra instance of OneDrive and forget about it until the next reboot, but there’s no way to disconnect it without logging in – and the account didn’t exist anymore.

Searching wasn’t helpful, since mostly I found info on how to disconnect from an account that did still exist. Or how to edit the registry. Not much help on a Mac. Even uninstalling and reinstalling OneDrive didn’t do it, because it just pulled both sets of credentials out of my keychain again.

I finally found an answer in one of the newer answers on this forum thread:

Remove additional OneDrive account on Mac

The main answer wasn’t helpful, but it turns out that, hidden inside the resource folder of the OneDrive app package, there’s a command to reset OneDrive! Yeah, you have to reconnect to the account that does still exist, but that’s both easy and fast!

In brief:

Close OneDrive

Find OneDrive in the Applications Folder

Right-click on it and choose Show Package Contents

Go into the Contents/Resources folder

The file will be either ResetOneDriveApp.command or ResetOneDriveAppStandalone.command. Double-click on it to run the command.

Go back to OneDrive and reconfigure the account that you do still have!

Thanks, Nevyn42, for solving the problem!
