I cannot get Outlook to connect after having installed the latest round of
Windows updates.

This included SP1 for Outlook 2007.

I get error code O X 80042109. I can send and receive from other computers
on the same home network that have XP installed.

Ideas?

After i installed SP1, i got an error like that, I did 2 things..

1 repair office
2 reinstalled office

everything works fine now, and i still kept the sp1 updates no problem. I just threw it in the fluke pile and went on.
