I have a Server 2003 R2 environment running Exchange 2003 (6.5.7638.1). I believe I need to change my default webmail URL to resolve an issue I am having connecting and downloading mail to devices using the webmail address from within my network. Everything works fine externally but fails inside the network.
I believe the problem is with related to my domain. Everything was originally setup as acmeva.com. We have since changed our public domain to acme.com without the VA but are still using webmail.acmeva.com as our webmail URL. webmail.acme.com will automatically forward to webmail.aceva.com externally but can't on the network.
I tried setting up an A Host record in DNS but the public IP gets in the way and wants to resolve to webmail.acmeva.acme.com, which fails.
Does anyone have any suggestions as to how I can resolve this and/or change my default webmail URL?
