Exchange 2010 install failing - Can't create Admin Group

Posted on 2011-03-09
Last Modified: 2012-05-11
I'm having an issue trying to install Exchange 2010 into my Exchange 2003 environment. See below for the error message. Basically it can't create the Exchange Administrative Group (FYDIBOHF23SPDLT) during the hub transport installation portion.

Also, in the past I had manually delete an Exchange 2010 admin group because the server failed and couldn't be restored. Could this be causing the issue?

Update, this is what is happening to me now (from another experts-exchange questions)

"Database is mandatory on UserMailbox error during install of Hub Transport"

Another suggestion was to try installing the other roles prior to the Hub Transport Role, so I also tried that. The Mailbox Role installed fine with no errors, as did the Client Access Role.

I then tried to install the Hub Transport Role again, and it worked! Rebooted server and then opened the Exchange Management Console, and voila, there it is, it appears we have Exchange 2010 again.

EXCEPT, now the mailbox role is failing with "Database is mandatory on UserMailbox. Property Name: Database".

I've tried deleting the FederatedEmail user account (per here, but when I go to recreate the account it fails.

This is another link regarding the issue -

It states I need to manually add a exchange db to the homeMDB for CN=FederatedEmail.4c....

How I'm I suppose to manually add a db value to homeMDB when no Exchange 2010 db has been created??

FIXED!! Using - 

Using ADSIEdit I put in the value of "CN=Mailbox Store (OLDMAILSERVER),CN=First Storage Group,CN=InformationStore,CN=OLDMAILSERVER,CN=Servers,CN=CCIC,CN=Administrative Groups,CN=XXXX,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=XXX,DC=XXXX,DC=XXX" for the homdMDB value for the federatedmail user/discovery.

This actually points two the old mail server that is still in operation (Exchange 2003). I put this value in for FederatedEmail.4c1f4d8b-8179-4148-93bf-00a95fa1e042 and  DiscoverySearchMailbox {D919BA05-46A6-415f-80AD-7E09334BB852} for homeMDB value.

After the install was done the homeMDB for FederatedEmail.4c1f4d8b-8179-4148-93bf-00a95fa1e042
changed to  CN=Mailbox Database 0562700375,CN=Databases,CN=Exchange Administrative Group (FYDIBOHF23SPDLT),CN=Administrative Groups,CN=XXX,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=XXX,DC=XXXX,DC=XXX which points to the new server. For whatever reason the homeMDB value did NOT change for DiscoverySearchMailbox {D919BA05-46A6-415f-80AD-7E09334BB852}

The whole reason for all these problems is that my first Exchange 2010 server failed (VM) and had to be deleted. By not gracefully uninstalling Exchange 2010 on this system it really messed up things in AD.
