Hi there,Last year our company trialed Exchange 2007 on a box call 'mail'. Since then the 120 day trial has expired.Now we are running up an Exchange server to deploy which we have called 'server2008'.When we open the Exchange management console. It displays the following exchange servers are unlicenced;Mail - 0 Days remainingServer2008 - 119 Days remainingNow that we no-longer have the computer 'mail' on the network, how do we remove reference to it on our new Exchange server?As some of the new Exchange server settings have been automatically configured to reference 'mail' which is obviously not ideal.Thanks in advance,Jason.

HI, you can remove Old exchange server as you remove production server. First move that OLD Exchange server holds any mailboxes and public folders to another exchange server then remove Exchange serve using Add/Remove programs.Refer below TechNet Article How to Completely Remove Exchange 2007 from a Server====================================http://technet.microsoft.com/en-us/library/bb123893.aspxRegardsChinthaka

Thanks for the quick reply.The challenge that I have is that I am pretty sure the reference to 'mail' is coming from the domain controller which is a separate server again.So, there is no reference to exchange in add/remove programs.Is there a registry key that can be deleted on the domain controller to get rid of the reference?Looking at the link that you supplied, this will get rid of exchange all together. So, I would like to keep exchange on my server called 'server2008' and remove the reference to the non-existant server 'mail'.Thanks for your patience :)

HI, Ohh, Did you remove your old Exchange 2007 server physically without proper remove?RegardsChinthaka

Yes, thats what the previous I.T. manager had done.

Hi,Given the current situation, the best way is to setup a new server, then use /m:recoverserver switch to recover the deleted server, then delete it in add/remove programs.
