Q:
How do you delete a user's Exchange 2003 mailbox with the AD Driver? Thanks for any help you can give me!
A:
Open ConsoleOne and locate the E-mail address property for the account.
Delete the e-mail address. In my tests, this successfully removed the Exchange provisioning from the account in AD. I believe this depends on the Recipient Update Service (RUS) running.
