Ive had this issue. its an add-in for outlook 2007 problem. For me it was a cyberlink add-in. Here's how to resolve.
click start
type outlook in the search bar
hold shift and right click on "outlook" in search results
choose "run as..."
when outlook opens, click tools, trust center
choose "add ins" from the left menu
at the bottom of the right page is the option to manage the COM add ins.
The one that caused the issue for me was just called "outlook addin" but if you look on the previous page, the location shows it to be related to the cyberlink dvd player. You need to run as admin to turn off most of these addins.
Then close and reopen outlook to test it. You may have to try a few different add-ins to find the one thats your problem.
