Here's an actual error message I got a few minutes ago. I'm not sure whether this should make me happy (at least they're being honest) or whether I should throw my computer out the window.
"Cannot start Microsoft Office Outlook. Cannot open the Outlook window. The set of folders cannot be opened. Microsoft Exchange is not available. Either there are network problems or the Exchange computer is down for maintenance."
