Hi, I have a question regarding a deployment of multiple HT server We have 2 Exchange server in our environment, both with a typical installation of the CA, HT, and MB roles. We have a DAG setup for the MB databases My question is, why is it that when I send mail from Server1, it gets submitted to the submission queue on Server2? If I suspend the submission queue on Server2, mail flow stops. How do I configure Exchange so that Server1 is the one handling sending/receiving emails?

This is by design with the HUB is located on a DAG member. Read the following: http://technet.microsoft.com/en-us/library/ff699049.aspx http://www.howexchangeworks.com/2010/05/routing-behaviour-change-when-hub-and.htmlTim Harrington - Catapult Systems - http://HowDoUC.blogspot.com
