I have a client that is running Outlook 2007 and we are running Exchange 2007. They recently setup an out of office auto reply to all clients outside of the company. After their vacation ended they selected the 'Do not send Out of Office auto-replies'.
How ever when every they receive an email from and address outside of the company the auto reply still sends an Out of Office message. I have checked the calander is set to dates in the past, there are no Rules in place related to the Out of Office auto reply function.
At this point I am not sure where to look to resolve this issue.
