I have a small pilot group of users on Exchange 2013, all other users are on Exchange 2007. Some of the pilot group have reported they get an Operation Failed error when they right click messages and try to mark them as junk. The same goes for anything that is in the junk mail folder they try to mark as not junk.
These same users were able to do this on 2007.
The affected users are running Office 2010 Pro on Windows 7 Enterprise. Is this issue caused by a missing patch/update or is there something else I need to do to fix this issue?
