Re: Outsourcing and Resource Forests

Carol-

I really don't think a 4000 user environment is going to put that much
pressure on your datacenter floorspace. 4000 mailboxes doesn't take *that*
much hardware.

Anyway, to answer your question, what you would do here is setup a forest
with the Exchange servers installed. You would create an outgoing trust in
this resource forest - that is, your resource forest trusts your corp
forest. Your resource forest would then have aduplicate account for each
user with a mailbox, but disabled. Finally, the dacl for the mailbox has the
corp account on there with full mailbox access and associated external
account rights.
