I gave myself full access on a mailbox that we are trying to monitor however when i try to open the mailbox, I receive the following error: "The set of folders cannot be opened. Microsoft Exchange is not available. Either there are network problems or the computer is down for maintenance"Any suggestions on why I'm receiving this error message?
