We are using the OneDrive for business sync app to synchronize our document libraries in SharePoint with our PCs in the office.

Recently, I came across a situation when testing where I entered my *personal* Hotmail credentials instead of the *organizational* account that had permission to access a document library. I knew it was not going to work but wanted to see what would happen so I could support our users if they ever made a similar error.

As expected, my OneDrive for Business sync app was then unable to authenticate with my Office 365 account and gave me a "unable to sync" error.

Unfortunately, **nothing** I subsequently did would make the sync app forget the incorrect credentials.

After realising there was no "log out" option in the sync app itself, I went on to try the following steps:

* deleted cookies in all my browsers
* uninstalled the OneDrive for Business sync app
* deleted all registry keys that I could find that were associated with the sync app (perhaps I missed something?)
* reinstalled the sync app (problem persisted in my Windows login)

*Microsoft's SharePoint support team were also unable to resolve the issue* during a remote support session of my PC and I ended up simply restoring my PC to a previous state. This is not acceptable as it may not be an option for a user.

I can't believe Microsoft made something that should be simple so difficult. With Dropbox you can do the same thing very easily.

Does anyone know how to clear the credentials associated with a user's OneDrive for Business sync app, or at least some kind of work around that doesn't involve having to recreate the user's Windows profile or restore to a previous system state?
