I'm having this problem with outlook and sharepoint syncronization and can't
seem to find an answer to it. Can somebody please help.

Scenario: I am using Sharepoint MOSS 2007 with Exchange Server 2007 (outlook
2007). I'd sync a sharepoint list with outlook 2007. However, every time I
open up outlook, it prompted me for my credentials even thought I have full
control access to the site and i don't know how to stop it from popping up.
