Removing last exchange server & exchange completely from organization

Posted on 2007-03-28
Last Modified: 2008-03-24
We have a development Active Directory domain with a single Last Exchange server Std version 2003.  We needed to install Exchange Server Enterprise version 2003 instead.  We didn't care about any emails or configuration on existing exchange server and wanted to run a clean installation of a new exchange server.  We have uninstalled the exchange server via Control Panel Add/Remove Programs.  Now when we go to install new Exchange Enterprise server it gives a message that we need to forest prep or do  not have exchange permissions.  We also get the same message when we try to run forestprep (even though account is member of schema/enterprise admins).  I think we need to run exchange setup /removeorg to clean out AD and then rerun forestprep and domainprep. Any advice?

do you plan to use the old databases with the new install?
if not then run the setup /removeorg to remove the exchange ORG completely from AD.
once that has been done then go into adsiedit.msc and check under configuration container, services, whether you see any thing related to your old exchange installation

Unless you want to change the Exchange org name, I don't see what removing the org information will do for you. All you will be doing is recreating the domain information that is already there.

Simply install the Exchange management tools ONLY on to a machine and then use the delegate control wizard to grant the account you want to use the relevant permissions. Then try the installation again.

Rakeshmiglani, I don't plan to use olddatabases with new install.   I have tried to run setup /removeorg  but it fails, error message ("The component "Microsoft Exchange Forest preparation" cannot be assigned the action "RemoveOrg" because you must be an Exchange Full Administrator at the organization level.  You must use an account that has been granted the Full Exchange Administrator role on the Exchange Organization using the Exchange Administration Delegation Wizard." ) Any ideas?
I shall check adsiedit tomorrow to see if anything is there?  Even normal reinstall does not work (similar error to above).  setup /forestprep and setup /domainprep also give similar error.
Sembee, I don't necessarily want to change Exchange org name.  
Question: Can one install Exchange management tools when there is no Exchange installed on the box (exchange has been uninstalled)??? You may be right as the error above does apppear to mean that delegartion permissions need to be set.  Should domain administrator not have permissions even without delegation?

You can install Exchange management tools with or without Exchange already installed. After installing it you will not see anything such as servers etc, but it will give you access to the delegate control wizard.

Your own name appears, and not Administrator?
Are you using THE administrator account for this work, or an equivalent?

Sembee, sorry I meant to say that administrator account appears there and I am logged on as administrator.  All I want is to install exchange fresh but even setup /removeorg does not seem to work.  Seems to be a problem with every setup.exe switch (forestprep/removeorg/uninstall)  Any ideas? Mark
