Subject: Hotmail NOC Contact

Hey All,

Does anyone have a good contact number for the Hotmail NOC? We've got e-mails from Hotmail to some of our customers being returned the Hotmail sender with a 554 error message fairly regularly. Our logs aren't showing any rejections, so we need to talk to Hotmail and find out what the 554 means on their side (there's no error description). Any help is greatly appreciated.

-J
