[OSL | CCIE_Voice] exchange server and AD cleanup for Unity

[Juan Lopez Hernandez -X (jlopezhe - IBM - INS at Cisco)]

Is there a nice way to clean up mailbox leftovers on the exchange
system? I used the 'Bulk Subscriber Delete' from the Unity toolbox, but
this only deletes Unity subscribers' mailboxes that are defined in the
Unity DB. Is there a way to clean up the message store completely, as I
get a 'system error' every time I want to leave a message and I think
it's related to adding new users on Unity, whose settings conflict with
leftover mailbox information.
 
What tool could I use to delete all mailboxes on exchange and all
(unity) accounts in AD?
 
cheers,
Juan
