why would my OneDrive suddenly be processing over 40,000 changes?

Same thing happened to me around February 19th 2025, on Windows 11 and for OneDrive Version 25.005.0112.0003. Maybe after the Windows 24H2 February Tuesday update... Processing 400000 changes. Very frustrating. I don't know why this suddenly happened.

Build 25.015.0126.0002 (64-bit)
185,000 files

Same issue with OneDrive version: Build 25.010.0119.0002

It is processing for the 2nd time today (this evening), after this mornings run completed ~2 hours ago, it took all day. As such, while it's running, it prevents other changes being upload to the cloud or when is does, there are conflicts that are produced and OneDrive end-ups with several file versions with the machine name appended at the end of file name.

Given these issues, OneDrive is NOT usable on the desktop/laptop. Ugh, frustrating to say the least.....terrible product and/or support from MS....

Three pages of responses since the original post over a month ago and no resolution?

OneDrive is like this dark mysterious thing that moves about in the shadows and has us all by the whaah whaahs, doing what it wants, how it wants and when it wants without explaining a single thing.

I'm at least down to 5000 changes to be processed but with no guarantee that it's going to do the trick.

Do the gods at OneDrive have an answer for us peons?

Update - I'm stuck at processing 36 changes now, with no movement. Pausing and restarting the sync makes no difference.

Same issue happened to me today, 28.02.2025. I noticed the problem when i tried to save a word file as pdf file to the same OneDrive folder where i opened it. Word gave "path does not exist" error when i pressed save button. Interestingly, i can reach folder with windows explorer and see all of the documents saved there and open any file. But when i try to save them to there again, word gave "path not found" error. I restarted my computer and tried again. Folder was reachable, files were working but i could not save there. I also noticed that Word was opening unusually slow when i opened word documents from that folder.

Therefore, i checked OneDrive app. My OneDrive (version 25.015.0126.0002) was stuck at processing around 10.000 changes. It was not doing anything. We did change only 5 or 10 documents recently.

So, I reset OneDrive. It gave me "We're resetting. Go ahead and keep working on your files...." message and started to process more than 50.000 changes. But it was not stuck this time. it nearly took half an hour to finish.

When One Drive finished processing changes, it gave me another error message as " we cannot merge changes in two folders, one folder is renamed as Design Docs-DESKTOP97RAF". Hundreds of files were lost in this new folder created by OneDrive. Original Design Docs folder is changed to internet shortcut???. I can no longer reach my shared folder from my computer. My shared folder can only be accessed from Web. I deleted this web shortcut. Afterwards, i tried to add shortcut from OneDrive web to same location. It only adds internet shortcut. I cannot work from my computer anymore.

What are you doing guys at there?
