Windows 7: Opening link problem in Outlook 2007

When I click on a link in an email message to open it, Outlook takes me to my homepage in Internet Explorer. This is a new problem, since it worked before. Any ideas on how to reset it correctly.

Can you do a system restore to a point before the problem occurred?

I did a system restore back to a week ago today. That corrected it. I don't know what I did in the past week, except some updates since SP1 was installed. Maybe thoses updates messed it up.

Windows 7 Forums - View Profile: mlomheim doesn't address how to do it in Windowsa 7. I did narrow down the culprit to a Microsoft Office Junk Filter update I did yesterday. That caused the problem, and removing the update solved the problem. I am not sure what the update was suppose to do, but it did cause this problem.

This is the update that caused the problem.
