I am using the exchange server that is included with Microsoft Small Business Server. I have a domain name that is just for the server and all users have their own email address (both local and internet email addressed - .local & .com). We also have a website that is hosted on a third party hosting server and email from this domain is retrived by our server with the POP Connector. I am receiving the email from my other server fine, but I would like to be able to send emails using my organizations domain name.
For the sake of this question, lets assume that the servers domain name is domain1.com and our website domain name (hosted by a hosting company) is domain2.org. All email sent to my domain2.org is retrieved by the small business server and put into my domain.com inbox. The problem is that when I want to send a new email or reply to an email sent to my domain2.org account, I have to use my domain1.com email - so the email looks like it's coming from domain1.com, which is in fact the case.
I want to set things up so that I can choose to send new messages and replies from either my servers domain (domain1.com) or my organizations domain name (domain2.org). I can't seem to figure out how to do this.
Is this possible, and if so, how would I set this up?
