When OneDrive for Business (ODFB) starts, you see the following error message: “A problem occurred while accessing the Office Document Cache. Do you want to repair this problem?”
Regardless of whether you choose Yes or No, the error keeps coming up. Also, on the Mac the computer becomes extremely slow, with CPU pegged.
- Close ODFB, close all Office applications, and close OneNote.
- Delete the “OfficeFileCache” folder and its contents.
- Restart ODFB. You should not get errors this time.
On Windows, you might have to work a bit harder to close ALL processes that are accessing the cache folder.
