We have Exchange 2007 server servicing 2 domains. Several mailboxes do not
have email addresses for the primary domain the server is in. That part is
fine however. Outlook 2007 keeps trying to convince itself that everyone who
gets mailed on that server should have an address on the primary domain and
keeps caching an invalid address. For example. Mailbox Staff has an address
(E-Mail Removed) however the primary domain the exchange server is in is
servicenetwork.com. No mater how many times I removed the cached autocomplete
address and hand type in
(E-Mail Removed) Outlook always saves the address as
(E-Mail Removed) and always trys to put that in first.
