I am using OneDrive for Business and Office 365 on Windows 7 and I am logged in with the same account in OneDrive and Office.
Snice a few weeks, I can't open Office files which are stored on my OneDrive anymore. Word (for example) tells me that the file has already been opened by another application even though it's not. The Problem doesn't appear with documents which are not stored in OneDrinve so I assume that this has somehow to do with the interaction of Word/Excel and OneDrive. I've had the problem appear also on my Windows 10 computer in my office. Has anyone seen this before?
