"Mark All as Read" in Outlook 2007 extremely slow

I recently upgraded from Outlook 2003 to Outlook 2007. The "Mark all as Read" option is something I frequently use, and worked fine in Outlook 2003 on my 3k+ messages Inbox.

Since upgrading to 2007, it takes well over 30 seconds for the action to complete... I am much better off just highlighting the unread messages and marking them manually. This doesn't seem right - anyone else experience this in Outlook 2007? Why would it be like this in 2007 but not 2003?
