I tried this advice from a user on another platform and it worked. thanks to the user named below for the ideas:
Here's a bit more info on what I did (Windows 11, 24H2):- As Krupička Lukáš described above, open a Microsoft app like Word or Excel, click on "open" and view the list of files recently opened. Find a file that is in the shared OneDrive folder you want to access. Right-click on the file and click on "Copy path to clipboard"- Open Windows Explorer (from the Start menu you can search for "File Explorer"), and navigate to your computer name. It should display you devices and drives, and any network locations you may have.- Click on "..." on the taskbar, and select "Map Network Drive"- In the "What network folder would you like to map?" window that comes up, click on "Connect to a Web site that you can use to store your documents and pictures." This will open a wizard that will help you create a shortcut to OneDrive. Click Next.- Click on "Choose a custom network location" and click Next.- In the "Specify the location of your website", paste (cntrl-v) the path that you copied in the first step above. (Mine started with https://d.docs.live.net/...)](https://d.docs.live.net/...%29 "d.docs.live.net") You may have to trim items off the end of the path if you want the link to go to a higher level in the directory structure than the path you copied. Click Next. It may ask you to enter the credentials of the OneDrive account the folder was shared with, and it will ask you to provide a name for the shortcut.- When finished this should create a Network Location shortcut that you can see in Explorer under your computer. You can use it from Explorer or from within applications to browse to locate files.Compared to the way OneDrive used to work with shared folders, it's pretty sluggish. I assume this is because the folder isn't mirrored locally and synched back to the server. This probably also means it will be more fragile in terms on network connection issues, etc. But for me, at least this gives me a somewhat clumsy way to get running again.Thanks to [Krupička Lukáš for the idea!
(if you cannot find a recent open file the original person that shared the folder can open a file from it then close it then view from recent files, right click and copy path to clip board. and now send link to all users that need to access the folder, trim back on the path as necessary.)
