Ok I have been rattling my brains for ages on this.
I have got Exchange 2010 working, and recently have noticed around 5 users out of the 150 we have, that they cannot access Out of Office assistant from there outlook 2007/2010. The error i am getting is as follows.
'Your out of Office settings cannot be displayed, because the server is currently unavailable. Try again later.'
I can access it via OWA, but not via the client. recently we moved from Exchange 2003 to Exchange 2010.
Can someone please help, as i have searched and have had no luck.
