Hi Guys,
Thanks for taking the time, I know this is a long post. But I figured details might help! :)
I ran into an often reported Issue with OneDrive Deleting Shared Folders from my Windows 11 File Explorer.
I had 4 Folders from different accounts shared with my Account (All members of my Family we are all together on a Family Plan) I linked the Folder online via "add Shortcut to my files" so that these Shared Folder would show up in my File Explorer on my Computer.
Now 2 days ago all of them got automatically renamed in my explorer and most of them deleted after and replaced with a link/Shortcut to the online Folder.
Originally it looked like below (Main and Main2 are the Folders from my own account which are Desktop and Mobile automatic Backups- Those two Folders didnt change throughout the whole ordeal):
Main
Main2
SharedFolder1 (200-600GB) mostly "online only";
SharedFolder2 (350GB) "Keep on device";
SharedFolder3 (200-600GB) "online only";
SharedFolder4 (200-600GB) Half of it "keep on device";
Yesterday Morning I suddenly saw that 600+GB of data had been deleted from my Hard drive - so I checked and found Following Folder Structure (It renamed some Shared Folders to "[Folder Name]-[Name of my Main AccountFolder]" and deleted most of the contents)
Main
Main2
SharedFolder1 (15GB);
SharedFolder2 (350GB);
SharedFolder4-Main (0GB);
SharedFolder3 |Link-Shortcut to online|;
SharedFolder4 |Link-Shortcut to online|;
At this time OneDrive said it is Processing 120.000+ changes.
A few hours later it had changed again:
Main
Main2
SharedFolder1-Main (15GB);
SharedFolder2-Main (350GB);
SharedFodler1 |Link-Shortcut to online|;
SharedFolder2 |Link-Shortcut to online|;
SharedFolder3 |Link-Shortcut to online|;
SharedFolder4 |Link-Shortcut to online|;
So In the evening it had deleted Shared Folder3&4 and replaced them with only a Link/shortcut.
Folder 1 Had been renamed and a Link generated. Expect for 15GB everything else had been deleted (those 15 GB might have been "always keep on device, and the rest could have been online files). In Folder 1 the Folder Sturcture and all the SubFolders are still there, just most of the content has been deleted)
Folder2 had been renamed but all the files were still on my computer, Folder2 was completely set to "always keep on this device" . Folder1 and 2 now show sync errors stating "You already have a File or Folder with this name in the same Location" I named them back From "Shared1-Main" etc. to just "Shared" but nothing changed.
In total about 600GB+ Of Space on my Harddrive freed up, So I know it didnt just delete online Files but also alot of Downloaded or "keep on device" files.
I cannot tell if the deleted Files were always on device or just Downloaded though.
- I tired restarting OneDrive several times.
- I unlinked and relinked the shared Folders online several times.
- I Deleted Onedrive from my computer reinstalled it and setup the Onedrive Folder in the same Place as before again. As I reinstalled OneDrive said "there already is a Onedrive Fodler on this computer, do you want to use it" and I clicked yes.
- I tried unlinking the account but it got stuck on "signign out" for several hours without actually signing out.
Thanks again, I hope somebody knows what to do :)
