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. Thanks!
