I am having the exact same problem brought up in this thread. One Drive tray icon tells me it is updating greater than 235,000 files AND I have not made any changes to my One Drive folders or files. Files are there in the Browser window, and in the Windows Explorer folders. The number of files being processed varies greatly meaning 100k changes up and down when I look multiple times. Once when I looked it said processing 8,000 changes. Now back up into over 150k. I think posting to a new thread is a dumb idea. It appears that this is the same problem for everyone that replied here. Of course maybe Md Nahid Sultan is trying to say to us that Microsoft will ignore our problem unless there are massive amounts of people creating the same post about the same issue.
