I checked to see if I had the update. I found two SP2 udates but not the one listed at Microsoft. Downloaded the update and a window opened up saying the update was already installed.
In Outlook 2007, you need to go to Tools, Trust Center, Add-ins.
Outlook seems to be working now. The add-ins that I couldn't uncheck are still checked. The Outlook shutdown add-in is asking to be purchased for the full program.
