Okay, first question from me, we are running exchange server 2010, with everyone on outlook 2010, we have a couple of accounts created used only for their outlook calendars, (called left board room and right board room) used to book in meetings. this was and had been working fine for months, now suddenly, outlook say :- Cannon open the free/busy information. Microsoft Exchange is not available. Either there are network problems or your exchange server is down for maintenance.
But I know that the server is fine, as everyone else is fine and all mail is going through.
Any ideas anyone?
