We are running a 2007 Exchange server with the most recent rollout. We have a CAS server set up. Recently after routine maintenance we have had users complain that their Out of Office (OOF) is not turning off.
Both Outlook and OWA show that the OOF is turned off yet the automatic reply is being sent out. It seems to be limited to one database but could be more wide spread then that.
I have run a test useing https://www.testexchangeconnectivity.com but that says that everything worked fine
How can this be fixed server side or is this something to fix client side?
