Exchange 2007 OAB Removal/Migration to Exchange 2013
I am trying to decommission an Exchange Server 2007 after a migration to Exchange 2013. While attempting to uninstall the Mailbox Role from Exchange 2007 from "Add/Remove Programs" it is failing with error: This Mailbox server is responsible for generating an Offline Address Book. Removal of the mailbox role is not permitted.
I'm not sure if the 2007 OAB data was actually migrated to 2013. I used ADSI edit to remove the 2007 Public Folder Database, so that data migration might not be possible at this point. Is that likely to cause problems?
What is the best next step to allow the uninstallation of 2007? Are there any Powershell commands to remove the OAB from 2007?

To identify the OAB Name I ran the command:
Get-OfflineAddressBook
from the Exchange Server 2013 EMS.
That returned two values:
Default Offline Address List
Default Offline Address List (Ex2012)
If I run the command:
Remove-OfflineAddressBook
Can I safely provide the first of the two values? I don't want to accidentally remove the 2013 version.

In EMS I ran:
Remove-OfflineAddressBook "Default Offline Address List"
and was then able to uninstall the Mailbox Role in Exchange 2007.

How can I identify the "OAB NAME" that needs to be moved? And if that does indeed fail, can you provide the command to remove it?
