Question : Exchange Email Address for Secondary Domains

Our exchange server is configured to accept email from several domains. For the purpose of this post we will call them primary.com and secondary.com, and tertiary.com. The majority of people only send email from primary.com and only need to receive email on secondary.com and tertiary.com. The majority of people are configured to have a single exchange mailbox with several email addresses. For users, that require the ability to send from secondary.com we have setup a 2nd mailbox with this email address and then forwarded all the email to their primary.com mailbox. For these users, on their mail clients, we have setup the secondary.com account as a pop account because the mail client will only support one exchange account. For the pop accounts we are not configuring the receive information and have only setup SMTP. This allows the users to select which account they are sending from in a drop down list.

Recently, a fourth domain was added to the exchange server. Initially we set this up the same way we had the other non primary domains. Unfortunately these users require to do the majority of their sending from fourth.com and not from primary.com. To accomodate this i changed the email address configuration. I put their fourth.com emaill address on the primary mailbox and their primary.com address on their the send as account (the account which is only configured for SMTP). This theoretically should solve the problem except that it doesnt work.

When i setup the primary account in entourage it connect to the server but no folers or email populate. If you check the event logs on the mac is shows a  "Warning: accessing obsolete X509Anchors."

I attached a shot of what entourage looks like when you try to connect to exchange.

I would appreciate any help anyone can provide.

Answer : Exchange Email Address for Secondary Domains

So thanks everyone for you help.

I will post the actual fix for this problem as it was rather strange.

First thing is that if you didnt select the option to support outlook 2k3 or entourage during the initial install of exchange 2k7 then you will need to manually create the "exchange" virtual directory in iis so that if people point to https://mail.mydomain.com/exchange the are able to hit OWA.

after you have done this in the entourage configuration for server address you need to put in a non standard address:
https://mail.mydomain.com/exchange/user@secondarydomain.com
you also must indicate their correct email address in the address field i.e. [email protected]

Once you put in these settings it magically connects and everything works.

Wow this took a lot of digging and i even called MS support although in the end they were not able to help me. Way to go MS.
