I am attempting to set an 'Out of Office' message on Outlook 2010 for a colleague (running 64-bit Windows 7). Once the rule is complete, I get a message which says that the rule is a Client rule and will only work when Outlook is running. I'm using Exchange 2007. How can I set it up so that the 'Out of Office' message will work regardless of whether Outlook is running or not?
To ensure full support of Outlook 2010, make sure to upgrade your Exchange server 2007 to Service Pack 3.
Outlook 2007/2010 relies on the autodiscover feature when handling Out of Office replies. Make sure you have autodiscovery set up and running correct: Test-OutlookWebServices and https://www.testexchangeconnectivity.com/ are your best friends when troubleshooting this
