Trying to uninstall Exchange Server 2003 causing 0x80072030

I had Blackberry Enterprise server installed on the Domain controller, but it has caused problems.

I have been able to successfully move BES back to its original server, but I also noticed that a full Exchange server information store was created on the DC.

When I try to uninstall Exchange I get the above mentioned error.

Following a similar experts-exchange listing, I was able to determine using ADSIEDIT that the original mailbox owner 'mail man' has been deleted.

How can I change the msExchAdminMailbox to an account that exists?

I never used any of the mailboxes on this server, because I never wanted the full installation of Exchange to occur on this machine.

The problem appears to be tied to the local machine's Postmaster account.
During an unstall check, we verify that there are no 'home MDB' values that
point to the local server. If there is one, we fail the install (its a
safeguard... really). The postmaster account is not that easy to find via
ADUC or the ESM unfortunately. The best way to locate it is to use ADSI
edit and navigate to this key:

CN=Configuration,DC=SUBDOMAIN,DC=DOMAIN,
DC=COM\CN=Services\CN=Microsoft Exchange\CN=EXCHANGE\CN=Global Settings\CN=Message Delivery

- Right click on "CN=Message Delivery" and click Properties.
- Find the attribute named "msExchAdminMailbox".

The value of msExchAdminMailbox is the user which owns the Postmaster
account.

- In ADSI EDIT, please try to find this user. If you can find it, please
open its properties, and check its HomeMDB attribute. Which Server is it pointing to?
It is possible that you cannot find this user in AD. Change the msExchAdminMailbox value to another user which mailbox is hosted in another Exchange Server.

Reboot the Exchange server and allow time for AD replication, then try the
uninstall again.

Huh?
The mailbox doesn't exist which is listed in msExchAdminMailbox

How would I change the HomeMDB attribute?

Did you know that by manually removing Exchange, so can leave disasterous results inside the Active Directory?

I found a non-destructive solution.  I tried re-installing Exchange, and then removed it and was successful.

I already responded to this question.

The solution is NOT to manually uninstall Exchange, because this leaves a lot of mess laying around in the Active Directory infrastructure.

THE SOLUTION was to re-install Exchange and then I was able to successfully uninstall the program.
