I had to reset Windows 10 on my Azure AD-joined computer, after which I upgraded from 1909 to 20H2. I now have OneDrive Build 20.201.1005.0009. Since then, I've had trouble reconnecting to all the SharePoint folders I was syncing with. For example, I'm a member of a Team with multiple channels. I was able to sync with the Files directory in one channel, but now when I try to sync the files in the General channel, I get an error: "Sorry, we can't sync this folder. You're already syncing a shortcut to a folder from this shared library." I haven't been able to find any documentation on this error. When I look at the Account tab in OneDrive, the channel that I am syncing with doesn't show up, so I can't stop syncing that channel in an attempt to get the new one.
If I click "Add shortcut to OneDrive" instead of "Sync" in the SharePoint interface, I get "Sorry, we can't create a shortcut to General because you already have one to a folder inside it. Do you want to replace that shortcut with General?" [Note: As far as I know, I did not have a shortcut to a folder inside General.] I clicked the Replace button, and that put a shortcut to the SharePoint library inside my OneDrive folder. That's not what I wanted -- I wanted the traditional separation between my personal OneDrive folders and my company's SharePoint libraries.
I see that the "Add shortcut to OneDrive" option is a relatively new feature that has been rolled out to our tenant. Was it intended to replace the SharePoint library sync function, or should we be able to use both simultaneously?
