Ok, this one is for the experts cause I'm stumped.

Have 4 Treo's in the same company that use SMS text messaging. Everything was fine, when you sent a text message your name popped up as the sender.

Changes made.....

We switched to a local Good-Link server for email and Outlook sync and now none of the SMS names show up within these 4 company Treo's. They appear only as the phone number. If someone outside the company SMS's us they appear as the name of the person like they should.
