Hi lamarque. Welcome to SevenForums.
Try and open Outlook in "safe mode".
How you do this is: Start
in (search programs and files), click on run
When the dialog box opens, type outlook /safe
. (note there is a space between Outllook and the forward slash).
Outlook should now open in Safe mode.
If Outlook opens without a problem you more than likely have third party programs that are Outlook aware running in the background.
Let us know what the result is.
