I have a client who is having problems opening excel documents that are in his Outlook 2010 (With Exchange 2010). Also if he saves them and opens them from the file system he gets the problem as well. It just started happening and he has no idea what has changed.
I found an article that described how to turn off protection, but the options aren't there which I presume is because he runs exchange?
He is accessing this account from within a terminal services session on a 2008 r2 server.
