How do I manually remove the exchange organization from active directory?

lbeg asked

Last Modified: 2007-12-19

A consultant came in this weekend to install exchange 2003 and when he encountered a mailbox error (he put the store on the wrong drive), he completely removed the primary exchange server and all exchange "delegate control" permissions without running /removeorg! Now we can't run forestprep, domainprep or removeorg without getting a permissions error saying the user must be an exchange full control administrator, which is bad b/c I'm running it as administrator, after reinstalling system manager and delegating those rights to that username.

Needless to say he's not with us anymore, but now we're left with active directory that can't process a new exchange organization. Is there any way to manually remove the exchange organization from Active Directory, or is there another option I'm not seeing?

Thanks in advance...

when u open adsiedit.msc do u see the exchange ORG under configuration container?


There is a "Microsoft Exchange System Objects" located directly under the domain root.

"ADSI Edit --> (server.domain.domain.com) --> dc=domain, dc=domain, dc=com --> CN=Microsoft exchange system objects"

what is your setup.. how many exchange servers. is this a single domain or do you have a parent/child domain setup?

you need to check the exchange org under the configuration partition.

you would see services and then microsoft exchange under configuration


1 Primary Domain Controller - 1 Exchange server both running as a DC using 2k3. Single domain.


Oops, I just realized what you are asking, and the answer is yes. Microsoft Exchange exists under services.

if u still see the ORG under microsoft exchange and then the ORG is present in AD

How to completely remove Exchange 2000 or Exchange 2003 from Active Directory


I've tried to run /removeorg and /forestprep and /domainprep. Domain Prep works, but removeorg and forestprep give me the following error:

The component "Microsoft Exchange Forest Preparation" cannot be assigned to the action "RemoveOrg" because:
-To install the first Exchange server in a domain, or to run setup in "/ForestPrep" mode, you must be an Exchange Full Administrator at the organizational level. You must use an account that has been granted the Full Exchange Administrator role on the Exchange organization using the Exchange Administrative Delegation Wizard.

I've run the EADW and added those users, but I get this message:
The process could not grant/change permission on this user.


Is there a way to simply manually uninstall the exchange organization using ADSI Edit?

if exchange is no more working and you want to uninstall exchange and reinstall the same. then

take system state backup
check the permissions on the exchange org object via asdieidt.msc
add the accounts that you are using there with full control
try running forest prep
