One of our users have a directory of Project files, where 50% of them wont open properly giving the error "We're sorry. There seems to be a problem with this file that keeps up from opening it. Please try using a backup copy if available." and you cannot access the file at all.
Weirdly, you can access the files via the recent documents tab in Project itself, this happens to anyone with a Project license in the company, does anyone have a solution or ideas for this?
