Hello Everyone. I have a question in regards to routing group. Not sure if I am on the right track, please advice . We have decided to configure multiple bridgehead server for fault tolerance, in our test lab I installed additional 2 exchange server called Mail2 and Mail3. Mail1 is the first exchange organisation in the test lab. I created a routing group called routing group A. I added Mail1 and Mail2 under the General Tab in routing group A properties, in the remote bridgehead server tab I added Mail3. I created user account testuser1 under Mail1 first storage group and testuser3 under mail3 server first storage group, testuser1 and testuser 3 can sent and received mail from each other, I disable SMTP service on Mail1. I sent a test e-mail from testuser1 to testuser3; the test e-mail can not reach testuser3. Please correct me if I am wrong, thought the purpose of having multiple bridgehead server if one server services down the other will take over the service. In this scenario SMTP service. May be I having mis- configure something. Please help Thanks Mr555
