Exchange 2007 accepted domain question?

I need to remove an accepted domain from my Exchange 2007 CAS\HUB and Edge Server,am I required to restart the transport service?
1 Solution
No, It is not required to restart transport service after removing accepted domain and e-mail address policy.
Using Exchange Management Console (EMC):

   1. Open the Exchange Management Console. Perform one of the following steps:  
          * On an Edge Transport server: Select Edge Transport, and then in the work pane, click the Accepted Domains tab.

On a Hub Transport server: Expand Organization Configuration, select Hub Transport, and then in the work pane, click the Accepted Domains tab.

You cannot modify the default accepted domain. To change which accepted domain is the default accepted domain, you must create a new accepted domain, and then set the new accepted domain as the default by using the Exchange Management Shell.

If you try to remove the default accepted domain from the list without configuring a different default accepted domain you will get an error:

In order to find out which of the accepted domains is the default one, you MUST use the Management Shell (PowerShell prompt) and run the following command:


From the Exchange Management Shell, then run the command

 restart-service msexchangetransport

A reboot of the Exchange Hub Transport Server would also be good option
Also Before you remove an accepted domain, verify that the domain name is not referenced in any e-mail address policy.

Just remove the accepted domain from HUB and the edge sync will replicate it to EDGE, if you have one. Don't try to delete on EDGE, it won't let you do that.

So what if I dellete the accepted domain on the edge server before the cas\hub server, willl I be OK ?
You said I would not be able to do this anyway so would I just try it first and if it does not work delete the accepted domain from the cas\hub server the run ; Start-EdgeSynchronization -Server <Hub Transport server name> on the edge server ? How long will it take to remove the accepted domain from the edge server?
