  • Hi everybody:

     

    I got the same rejection message. Tried to follow the procedure, but my Echange Management Console doesn't show the Edge Transport option in the tree. 

    I am using SBS2008, Exchange 2007 & Forefront Protection for Exchange Server. Is it maybe because, I should make that kind of modifications in Forefront?

    Your help will be more than welcome.
