Exchange Server

Does anyone know how to setup exchange to forward mail to an alternate
address ? For example mail comes into user@abc.com but need to be routed to
user@def.com. Any suggestions would be appreciated.

If I understand the question you need your exchange server to receive mail
for multiple domains and deliver to the proper recipients. You do this with
the "Recipient Update Service" and "Recipient Policies". You can configure
additional policies to accept email and set multiple email addresses for some
or all user accounts. We have some users that receive email at 2 different
email addresses and if you send an email to either user1@mydomain.com or
user1@child.mydomain.com the same user will get the email. We did this for a
child domain however you can do it simply by configuring a group for the
users with different addresses. If it's everyone then it will be even easier.

Sorry but configuring either of those is more than i would try to go into
here but run a search on those and the articles are fairly easy to follow.
Hope that helps,
Michael

Hey Michael,

Thanks for your response BUT not EXACTLY. Here is what is happening. We have
multiple domains for 3 different companies ALL under the same company name
but with 3 different offices (all owned by different principals). So we have
our umbrella (example) company who wants everyone's email to be
@umbrellacompany.com, this is the main owner for the business. The other
businesses kind of like a franchise have abc.com and def.com. The main
company wants everyone's email to be theirname@umbrellacompany.com. The
problem is abc.com and def.com already have domains and servers running in
their offices and refuse to change their email addresses. SO I recommended
that umbrellacompany.com simply accept email for whoever@umbrellacompany.com
and then put a forwader in to point that mail to whoever@abc.com and def.com
depending on the recipient. All of these offices are NOT connected to each
other. I suppose the simplest explanation would be if I am
dana@vciservices.com and I leave the company and the company says it's OK to
keep my email but i want it to go to dana@yahoo.com, that type of forwarder.
Thanks for your help.

Dana,

The orginal concept although workable sounds a very tedious, especially if
the mail would be forwarded out immediately onto the internet

I think this is what you need...
The pre-req: (1) Network connectivity is established between the offices
involved, otherwise you'll have to configure SMTP connectors to the smtp
gateway for these external offices - we'll come to that later. (2) ALL users
are configured with the umbrella email address as a proxy smtp address

The solution: Once OfficeA (your office) is configured to receive messages
for the "umbrella" address which seems to be in place, the next step is to
configure mail delivery to one of the downstream offices by using an SMTP
connector, and specifying the same e-mail address space. (one note of
importance, make sure your Exchange organisation is not configured as
authoritative of the email address - Recipient Policy settings - email
address properties). The SMTP connector needs to be configured with the a
smart host referencing either an internal address (networked offices) for the
receiving server or external addtess (mx record details) for the first office
(call it OfficeB). At officeB a similar SMTP configuration needs to be in
place referencing OfficeC

Mail delivery first comes to your environment; if the user does not exist in
your exchange organisation, the mail is then routed through the smtp
connector to OfficeB. If the user exists in OfficeB then all is well. If not,
then OfficeB will further route the email over it's pre-configured SMTP
connector to OfficeC.

So the environment looks like this:

OfficeA over smtp connector to smarthost at OfficeB
OfficeB over smtp connector to smarthost at OfficeC
OfficeC is endpoint for mail delivery or @umbrellacompany.com address, and
is authoritative of the smtp domain (Recipient policy email address
properties)

**There is a massive assumption here that all offices are running Exchange
2000/3 systems

Let me know how you get on.
Eriq.
