Wild card certificate and Exchange 2010 RRS feed

  • Question

  • Hi Everyone!

    I have a client who is using a wild card certificate for Exchange 2010. The internal domain name and the external domain names do not match. For instance internally it is client.local and external it is myclient.org. The certificate is for *.myclient.org. Is it even possible to use the wild card certificate so that the internal Outlook clients do not receive the certificate error?

    There is an internal DNS zone created that matches the external zone due to issues with the old domain.

  • Your last sentence is the key.  You are utilizing a split namespace.  This is good.  It means you can set all of your urls to the same values externally as you do internally.  Then just control where the traffic actually goes with DNS.  This way, Outlook connects to the namespace that's on the cert.
