Hi i have installed exchange certificate sucessfully. but in the domain names, i had just specified external DNS names. now when connecting from the outside, i can connect without any errors/warnings.
however, when connecting internally (LAN), i get certificate warnings, as the internal name of the server is not appearing in the certificate.
i am wondering what is the easiest solution to this.

Purchase another SAN certificate with the correct URLs on it and remember to include autodiscover.domain.com as one of the URLs

hi Thanks for your post. i do have autodiscover in my certificate that i have bought, and it works well.
however, i have a problem with internal DNS. can i assign a certificate that is signed by my local CA to IIS for this. i assume that this would be a problem since i have already got a certificate asssigned to IIS from external CA.

Unfortunately not! IIS web sites can only use one certificate. Make it easy for yourself (but a little more expensive) and just get a new certificate with the proper names on it.

You could always configure split-dns to save the expense of another certificate.

The main drawback being that when DNS changes occur for outside accessible services/hosts, you'd need to make the same changes on the internal DNS server.
