Exchange and multiple domains.

Ok, we have a couple of domains and are wanting to use a single exchange server. I have read that all of the accounts have to be created on the exchange domain and just give trusted accounts permission.

I just wanted to confirm this...I have a friend that told me there was some way to mail enable users in domains other than the exchange server.

Thanks

Exchange server is forest wide application.

you can have N number of domains in exchange server. eg : abc@microsoft.com, abc@google.com, abc@dominic.com etc....... all in one exchange server.
Do you need this ?

What I have now is:

Domain A = No exchange server

Domain B = Exchange Domain

A two way trust between the two. I am able to browse AD from the exchange server, but I have several users in domain A that I want to have mailboxes.

I have set up multiple UPN suffixes and security groups and have recipent policies set up to deliver mail to them, but these users are all set up on the exchange domain.

<a href="https://www.experts-exchange.com/questions/21556972/exchange-server-in-multiple-domains.html?query=mail+enable+trusted+domain&clearTAFilter=true">This Link</a> is what made me think that users in the other domain would have to have their own accounts in the exchange domain.

This is all on Windows 2003 servers and Exchange 2003 also.

As I said Exchange is forest wide. if you have multiple domain all you need to do is run domainprep in all the domains. BY running domainprep you will make that domain aware of exchange server in the forest and when you create user in that domain it will prompt for creating exchange mailbox.

forestprep is already run and the schema has already expanded. so no need to run it again.

also you need one RUS per domain in your forest.

waiting for you response...:)

What if the Exchange server is in another Forest?

Forget trusts thats only for domain authentication.... etc... exchange knows no boundries when in a forest.
don't forget domainprep !!!!! run it on the DC in the doman thats all.....

I was searching for it the wrong way, I eventually got to the EAA feature in exchange and got it to working.

Thanks again
