This message started popping up some time yesterday afternoon, and constantly keep appearing in the Windows notification area.
I have tried to use “Add a OneDrive account” in order to refresh the login, to no avail. I haven’t changed any InSync settings, or changed my OneDrive password, so I can’t tell what prompted this issue.
Any steps I can take to resolve this?
I have tried the “Alternative Login” button. I followed the instructions, which resolves the error only for a short while.
