If your workstation has your SharePoint site(s) mapped as network drives, then you may have seen the below error appear recently.

The error appears when attempting to access the mapped drive or files on it. After a few minutes, the error goes away and the mapped drive will work again. The error may appear multiple time per day for multiple computers. The error also may appear regardless of whether the computer is in the office or remote.

We are aware of the issue and have determined that the problem is on Microsoft's backend servers. We will continue to monitor the situation as it develops.

To work around this error, you can access your files by either going directly  to your SharePoint site, or waiting a few minutes for the mapped drive to start working again.
