That sounds like a fine patchwork solution for the time being, but I
wouldn¹t suggest you plan to rely on it for long.  Using CSVDE on a regular
basis will eventually evolve into users calling for problems with missing
recipient, which will lead to running your imports nightly, or even more
often.  Eventually imports and exports wind up breaking / masing / missing
something and lead to grief you probably don¹t need.

If you put a trust in place, you could then look at migrating mailboxes to a
single org (presumably DEF.COM) and continue to use the same user IDs by
using the associated external account flag.  See

This still isn¹t a long term solution (nor was it ever intended to be) but
it gets around all sorts of potential problems with GAL syncs, repliability,
and delegation.  Eventually, though, you need to consider a long-term
approach, unless you are anticipating a quick divestiture.

Hi Prabhakar,
 
Thanks for your input?
 
Yep? It is Win2k3 Native mode? But do we need trust for this? If so why is
it needed?
We have just planed to use the Exchange in a Hub & Spoke topology for
relaying the mail for multiple organizations.
 

We can export and import the users using CSVDE tool on regular basis or in
future we have plans to use IIFP?
 
Regards, Mahadevan

Hi,
 
I have a question...
Assume that a company is acquiring another company which has its own Forest
and Separate Exchange organization. The SMTP domain ID for the acquired
company is @ABC.COM and the Existing SMTP domain ID in this company is
@DEF.COM. We have added DEF.COM to ABC.COM through Recipient Policies and
have set DEF.COM as the primary address so that all the Reply to address
will be DEF.COM. Now the requirement is all the mails which are sent to
users in the recently acquired company should be relayed through the Mail
Server at DEF.COM. 
 
After setting up the proper MX records, is it enough if we have the contact
objects for the ABC.COM users and a SMTP connector which will forward the
mails to the mail server in the ABC.COM domain?  Plz advise if I am missing
out something?
 
 
Regards, Mahadevan
