I've inherited an unusual set up. the previous email admin installed 1 Hub Transport,Client Access server 2 Hub Transport, Mailbox servers This is causing me all kinds of head aches as I only want email going out through the HT,CAS server. My quesion is this, can I uninstall the HT from the Mailbox servers without causing any problems? Will email start going through the HT, CAS server after I do this? Thanks

You can do Set-MailboxServer -Id: mbxserverA-SubmissionServerOverrideList: htserverB,htserverC or just uninstall the HT roles on the MB servers. There is no issue or impact of uninstalling. Will email start going through the other HT after? You want to make sure you rehome all your connectors before you uninstall though I imagine when you uninstall it may error out notifying you.

Thanks James, Will I use that command on the HT servers that I want to uninstall? sounds like an obvious question but I want to make sure. thanks

You would use that command if you didnt want to uninstall your HT roles on your MB servers but wanted your MB servers to use the other HT servers to route mail. If you want to just uninstall you don't need to run the command at all, just uninstall. James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com
