Microsoft OneDrive for Business stops sync with error the server you are trying to access is using an authentication protocol not supported

After a local windows password change, OneDrive for business stopped working with error

- the server you are trying to access is using an authentication protocol not supported

This error also kept pooping up during random times (guessing onedrive was trying to do a Sync)

Turns out the cached password is not updated in the Windows credential manager.

To Solve

Go to:

1. Control Panel
2. User Accounts
3. Credential Manager
4. Windows Credentials
5. Look for the credential thats named like Microsoft* and on expanding the username matching the one you use to login
6. Delete this credential. If in doubt, you can delete all of them and no harm is done as windows will ask for the credentials again as needed
7. Now, go to onedrive.com, and login as usual. Once on the One Drive page, click Sync
8. this should open your local OneDrive for buiness app and it should start normally at this time

I encountered this problem with Office 2016 on Windows 10, and this might be a problem for other versions of Office as well
