I am new to Exchange and just setup a trial version of Exchange Server 2013.  I was able to get it configured and working with one domain. (domain1.com)

Now I want to be able to manage email addresses for multiple domains.

Right now we are using POP email accounts and several users have 2 .pst files open at the same time in Outlook.  For example a user will open Outlook and be able to send and receive email from user@domain1.com and user@domain2.com.

Can I do this with exchange?  I can see how to add multiple addresses to one mailbox, but I'm wondering if there is a way to create multiple mailboxes for one user?

Exchange does not have a POP connector.  Small Business Server did, but I don't know whether it is still part of the package.  You might ask in the SBS forum.

POP3 is a single mailbox client mail retrieval protocol, not a mail transport protocol.  Any attempt to use it as a mail transport protocol is a great big kludge.  Exchange is designed to connect to the Internet using SMTP.

I found another article online that dealt with Exchange 2003, but I think this should work for my situation.  Basically they said to create another user in active directory and then give the user that needs access to two different addresses control of both mailboxes.  They can then connect to 2 mailboxes within outlook and send an receive from both addresses.  I only have two users that require multiple mailboxes so this is they direction I'm leaning unless I come up with a better solution.

Just thought I'd share.

 

You don't need to create two mailboxes to receive from two addresses.  A mailbox can have a virtually infinite number of e-mail addresses.  But it does make sending from two addresses easier.

That's the main reason I need to do this. because I have users that need to be able to send mail from multiple addresses.

You didn't say that in your original question, sorry.
