Our exchange server domain is

The way this has been setup (by an external company) is that if I try to browse to our website using rather than I am directed to the main exchange box, rather than our actual externally hosted server.

As we would like to drop the www, is it possible to setup a DNS record to that host without breaking the rest of exchange functionality. That server has it's own dns name of

It sounds to me like there is an A record for the domain that points to the ip address of the Exchange server. Change the domain A record to point to the ip address of your web server. This won't affect Exchange except for the fact that people who are used to typing to get to OWA will now have to type (or whatever A or CNAME record you set up to pint to Exchange).

oops. I forgot about the SSL cert for OWA and RPC over HTTP. Are you using SSL and if so, what's the friendly (common) name of the current cert?

You need to edit the CNAME record for "" to point to the correct server in your DNS records.

To amplify: change the CNAME record for to that of your external web-server. – sysadmin1138 Aug 5 '09 at 5:53
It's going to be an A record, not a CNAME for unless they have a pretty weird setup. I'm not even sure it's possible to CNAME at that level but not 100% sure it's impossible either. – Zypher Aug 5 '09 at 19:41

Unless your Exchange server is using name-based hosting, the biggest hassle of moving it from to is getting new SSL certificates to reflect the new name. Everything else should just work.
