Exchange 2007 uninstall and AD cleanup - 27.Aug.2014 10:41:02 AM

We recently migrated to hosted exchange environment offered by a third party provider. So, I decided to uninstall/remove the in-house Exchange 2007 Standard SP3 that we had. Half the uninstall went smooth through "uninstall" option in the "Programs and Features" under control panel (running Windows 2008 Std SP2).

I say "half the uninstall went smooth" because when it came to uninstalling the Hub Transport role it kept asking for original installer for "hygine" (i believe it has something to do with the anti-spam tool). Anyways, after lots of Googling I found out that by using the MsiZap tool I can by-pass that window where the installer requests for the source files. After I did that, the Exchange uninstaller came back and said it removed Hub Transport role and other roles which I had unchecked.

However, when I take a look at ADSI now, under CN=Configuration I still see CN-Microsoft Exchange and everything underneath it. We always had only one exchange server in-house and we don't have any plans to install an exchange server anytime soon. However, I like to have a clean AD and remove any references to the old Exchange server we had, so that in the future IF we decide to install an Exchange server we don't run into any issues.

I was hoping the uninstaller would have done a good job of cleaning up all exchange references i AD. But, obviously that's not the case here. Any idea what can be done now to keep the AD clean of any Exchange references?

You have to first remove the exchange server machine from the Send Connectors of the Exchange Organization then you would be able to remove a Hub Transport Server Role and all AD Exchange references.
Start Exchange Management Console
Expand Organization Configuration
Select Hub Transport then open Send Connectors tab
After that, open each of the Send Connectors listed there.
Go to the Source Server tab
Select the server you want to uninstall the Hub Transport Role
click Remove

You can remove Microsoft Exchange Server 2007 from a server by using the Exchange Server 2007 Setup wizard or the Setup.com command.

The detailed procedure is given here: http://technet.microsoft.com/en-in/library/bb123893%28v=exchg.80%29.aspx

Thanks! I seen that guide and have followed it already. I have done what you suggested even before I posted on this forum. Like I said before everything appears to have removed.. Now when I go through the Uninstall wizard of Exchange 2007, I see "Mailbox Role", "Client Access Role" and "Hub Transport Role". I uncheck all of them and hit next and it comes back and says "The following server roles have been successfully removed". I hit finish. I can go back to the uninstall wizard and do the same thing over and over and everytime it says "it successfully finished". So, I am not sure if it doing anything at all... and when I look at the ADSI I still see CN=Microsoft Exchange container which I was hoping it would be gone (to tell me that the Exchange is cleanly removed from this organization).
