Accepted domain configurations in Exchange Mail server

Dear Experts, we have a mail Exchange domain for example: ABC.com. After that, we configured accepted domain and email address policy, so that another domain ABC.net could send emails via ABC.com mail server.

However, when user typed in their web browser: https://mail.ABC.net, it redirected to https://mail.ABC.com. We knew that is expected behavior with the setting but how can we configure so that we have a separated page: https://mail.ABC.net instead of ABC.com?

Many thanks in advance!

To have a separated page you would need to create the "urls" or the Service Entry Points for Exchange.

You will always have just ONE address set active (it can be either, ABC.net or ABC.com), just one of them not both.

But if you configure the following records in the SSL and internal/Externals DNS
autodiscover.ABC.net
autodiscover.ABC.com
Mail.ABC.net
Mail.ABC.com

you are able to enter into the ABC.com and set the A record to the public IP of the server, as well as the CNAME for autodiscover for each domain.
that would do the trick.

You need to add an UPN suffix, or did you already do that ?

Hi ferrarista, No I have not added it yet. I thought it just have effect on local domain environment only, am I right?
What I need is when users type in https://mail.ABC.net, it will show up the ABC.net page, NOT redirect to ABC.com

Hi Jose, Yes we had SSL certificates and in the public DNS, both of these A records point to 1 public IP address of ABC.com mail server:
autodiscover.ABC.net
autodiscover.ABC.com
Mail.ABC.net
Mail.ABC.com

What is Service Entry Points for Exchange? Does it require coding or just some configurations on Exchange server?

That will SCP point. You need to set it on CAS server. To change ECP access page, you need to make a change in ECP virtual directory URL Moreover, you may set another virtual directory url too.


As Jose said, you can have only one URL, you can't make both works.

Hi Hasin, do you have any reference link, please? Our diagram is simple: just 1 AD + 1 Mailbox Exchange Server.

Is that okay to configure SCP on Mailbox Server? How can I set set another virtual directory URL?

Reference link on how to change ECP and OWA URL. Also setting autodiscovery. You will need certificate (internal as well third party ) to have new domain value if you are changing the URL name or else it OUtlook will give the prompt.
