Unable to Delete Doc Library synced folder from Windows Explorer

David ChamberlainThanks. This works on most folders, but not on all. Two folders refuse to disappear from the Windows Explorer view. A pop-up windows displays this error: 

Title: "Location is not available."

Error text: "C:\users\<abc>\<sharepointname> - documents\<channelname>\<projectname>\...\ABC is not accessible. The tag present in the reparse point buffer is invalid."

I found a post on that error on this link. 

In the above path, <abc> represents my user name, <sharepointname> represents a SharePoint site of which I sync the entire document folder to Windows. <channelname> is a document subfolder and also a channel in Teams. <projectname> is the name of a project. The entire path C:\...\ABC is a 14-level deep folder tree. ABC is the lowest level folder and contains no files. 

The relevant history is that this folder structure had contained project documentation, but the full tree, starting from <channelname> on down had been moved to a new SharePoint site. The path above was the longest one in the tree, and perhaps this triggered a bug.
