Download / Installation:

You can download the tool from the following location:

Remove Exchange Attributes Tool – Version 1.0 – [11KB]

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.

Requirements:

• .NET 2.0
• Exchange 2007 / Exchange 2010 (tested against the RC build)

Usage:

NOTE: 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 good reasons (like the examples used in this article).

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!

The tool weighs in at 11KB in size and when executed (from the Windows Command Prompt) require two parameters: which are as follows:

<mailbox samAccountName> operating mode which is either <info> or <remove>

Therefore and example execution would be:

RemoveExchangeAttributes.exe administrator info

or

RemoveExchangeAttributes.exe administrator remove
