Secure Certificate for Exchange Problem
Posted on 2014-02-05
I have an external domain aaa.org and our internal network is zzz.net. Users accessing email using mail.aaa.org/owa from outside our network have no problem. However, users on our internal network connecting to email through outlook 2010 to server.zzz.net running Exchange 2010 get an error saying:
The name on the security certificate is invalid or does not match the name of the site.
This error occurs because the domain zzz.net is not on the certificate. We can't include the domain zzz.net on the certificate because the network is internal and is not registered with whois.
Can you tell me the best way to configure this server so that users on the internal network do not get this certificate error? I'd rather not go with a split DNS zone if at all possible, as that raises other issues.
Thanks in advance for your help.
