While on vacation a number of you let me know i have two out of offices being sent - one accurate - one over a Year old! Turns out the one that is a year old was created in a custom internal tool and wasn't visible to the Outlook 2007 Out of Office Assistant.

To fix this i needed to use a switch called "Cleanrules" on Outlook.exe.

-Note do NOT run this until you have backed up your existing rules!

 

For more  information about this switch see:

Rules That You Created in Outlook 2002 Are Not Visible in Outlook 2003, but the Rules Are Visible in OWA
