I've inherited an SBS2008 box that is exhibiting a couple of weird (I suspect related) issues in the Exchange Management Console. When you try to view the Properties of any mailbox the dialogue appears but all the fields are blank on the General tab, and you can't select any of the other tabs or click any buttons.
Similary, attempting to view/set the 'Full Access Permissions' on a mailbox produces nothing whatsoever, i.e. no dialogues, no errors, no hour glass etc... However, you can view and use the 'Send As Permission' without a problem.
I'm at a bit of a loss where to start, but I'm wondering whether someone has fiddled with permissions somewhere along the line? Any thoughts/suggestions are much appreciated!
