The tag present in the reparse point buffer is invalid

I ran into this issue recently where some files and folders were not accessible in using the File Explorer, command prompt or even PowerShell. When trying to open / rename or delete the folder the following error pops up:

The tag present in the reparse point buffer is invalid

The files / folders were located in OneDrive for Business and enabled for the on-demand feature. Based on saome other blogs, those files / folders are junction and got in a bad state.

OneDrive For Business/SharePoint Sites Trouble shooting

Syncing problems with Office 365 SharePoint sites – sometimes they’re easy to resolve and sometimes they are very difficult, tedious and nearly impossible to resolve (unless you are very well acquainted with SharePoint-speak and have some pretty deep networking/IT/Microsoft knowledge). This is the story of how I resolved a tough (for me), syncing issue with O365 SharePoint sites.

Problem

The problem: client said some of their SharePoint sites would not finish syncing. They noticed their blue icons had the syncing notification going constantly and it would never finish. They tried using the repair OneDrive function. One user reported their SharePoint site names were changed to a generic (Site1…., Site2……) and so on. The other user did not get that, but it didn’t fix the problem either.
