Are you perhaps using Norton Internet Security or some other suite? Check
your COMs and Add Ins for any integration into Outlook. Not just antivirus
but even anti-spam.

I've the same experience. It's comes each time after installing
Outlook updates from the Microsoft, which I've got it yesturday.
Every time I do the same thing - I'm uninsalling it, and prohibit this
update. Everything works after that. Seems like Microsoft guys release
not well tested upgrades for Outlook. I didn't found any meaningful
explanation/fix for this bug in Internet ;(
