Users in our HR department keep complaining that they receive an error almost every time they try to open an MS Office file (xls, xlsx, doc, docx, etc...).
I have verified the problem and I checked the usual suspects: no orphaned owner files, no open files are listed on the file server. I even reset user permissions for the file share (forced reinherit).
This occurs regardless of which file is opened, but only seems to happen on this one mapped share. Here's a sample screenshot of the error.
