Folder shaing across domains

[Fred Flintstone]

I have 2 AD forests with full trust. Each has its own domain and
exchange server. I'd like a user from domain1 to share a calendar
with a user on domain2.

I'm currently using the sync util to synchronize certain public
folders and I could create matching mailboxes on both servers but
legally these 2 domains have to mostly remain separate. I can't have
the CEO of one company having a full synced mailbox on the exchange
server for the other but they need to see his calendar only.

Is this possible and how would one do it
since one Exchange server can't see the other's information stores?
Or is there a way I CAN have one see the other?

Thanks!

This would be a very good question to post in
microsoft.public.exchange.admin, and include your versions of Windows server
& Exchange, and SP levels, etc.

....and it's not possible I gather. It seems I have to replicate the
mailboxes between organizations.

Ah, well, that was silly of them. This has nothing to do with
Outlook.....it's a server/network issue.

There's no native way to do this. The most you could do is allow the users
in one domain to access a mailbox on the remote Exchange server....and/or
vice versa.
