Dear friends,

My requirement is to add additional domain name url for OWA for my exchange 2013. Let me explain:

Currently my public url for OWA is mail.domain.com and now i want to add additional name like mail.domain2.com . I have added additional suffix and create users for this, now the remaining part is the url for OWA. I have created dns entries in godaddy and i have the ssl certificate for both the domain names. I can access the owa using the another url domain but hitting certificate error.

Please help.

Hello

What is error concrete certificate error?
name erro or trusted error?

it is trust error.Becoz the cert i have installed in the server is for the first domain url.ie for mail.domain.com.Is there anyway i can add the new ssl cert for the new domain url.

Hello

SSl certificate is public certificate or create own CA server?

Hi,

From your description, the issue is related to the certificate. I would like to verify if you have one CAS server. If yes, you can create these two names in one certificate and check the result.

What's more, here is a helpful blog for your reference:

Hope this can be helpful to you.

Best regards,

Did you get a new cert for just the new domain? Or a new cert covering both domains (a UCC cert)?

If it was just for the new one, have a look again in IIS at the cert for the default web site.  You might find that adding the new one kicked the old one off.
