Yes, if they host your public DNS.

You will need to create a subdomain webmail of your main mydomain.org domain. Then, once your subdomain is created, edit its DNS so that its A record IP address is pointing to the external IP of your system (probably the same settings as mydomain.org)

Once changes have replicated through the DNS system and assuming you have the correct ports open in your router firewall (port 443 for HTTPS), you will be able to go to webmail.mydomain.org/exchange.

My only word of caution is if you have an SSL certificate from a company (Verisign, Godaddy etc.) then this may only work for mydomain.org or www.mydomain.org, I believe it is only the more expensive ones which allow you to have a wildcard in there. Therefore, if it is for mydomain.org, attempting to access webmail.mydomain.org will produce a certificate warning saying that the name of the site doesn't match the name on the certificate.

Or, just add an A record for the hostname webmail to the existing domain mydomain.org .
