This tool will allow you to forcibly remove the Exchange attributes from a user account in Active Directory.
This tool is destructive! – it will forcibly disassociate a mailbox from its AD account – this process is not easily reversible and should not be performed unless you have a good reason.
This is very much use at your own risk – neither Microsoft nor I will be able to support you if something goes wrong – it should only be used in the most severe of circumstances – you have been warned!
- NET 2.0
- Exchange 2007 / Exchange 2010 (tested against the RC build)
You can download the tool from the following location:
It should be downloaded into “c:\RemoveExchangeAttributes” – on either a Domain Controller within the Domain where the previous mailbox server was resident or onto the new Exchange Server.
