Associating mailbox with an external account

Hello - Can anyone help please?

We are in the process of migrating our source Active Directory Dept.BIZname.local to our group Active Directory Group.Com (The target)
We are only migrating the AD objects using Quest Migration Manager for AD.
Our Exchange 2007 environment remains in the source domain for now.

How can I associate the user’s mailboxes in the source domain with their accounts in the target domain ater migration?

It needs to be enabled in source when the migration session runs.  QMM will only do the work it needs if it does the disable action, and it won't do the disable action if the object is already disabled.

In QMM if you do a migration session of the user, and in that migration session you enable target and disable source, then QMM will automatically set the appropriate permissions to allow your source mailbox to be accessed from the target user.

Thanks,

Hi Michael - Thank you for your swift response.

I tried what you suggested and the user was able to open outlook alright and received email from other users. But when he reply to any incoming mails he received an NDR that he does not have "SEND AS" permissions contact your Administrator. Any thought on that?

Well you can try ADPW, but it should not be required.  Are you using two service accounts in your domain pair?  Any errors in the dsa.log when you do the migration session?

Yes I am using two service accounts in my domain pair. One for the Source and one for the Target. I will check the dsa.log and let you know.

Many thanks

Try running Active Directory Processing Wizard (ADPW) on the Source?

Just to be clear, source AD account is disabled, and it was disabled as part of a QMM Migration Session?
