Webmail from same domain different site (AD Site)

Hi -  I am attemping to access the company's webmail from the same domain, but a different site (AD sites and services) - site Z.  IN sites 's  dns forwarding zone an A record was added with the proper public IP address of the mail site (OWA) being served from company HQ - Site A, however it is not working.  Anybody experience this before?

OK, do your clients in that Site use that Site's DNS IP address as primary DNS ? Looks like they have configured DNS server from other Site (I guess).

If those settings are issued by DHCP server, go to Scope/Server options (depends on your configuration) and modify option no 006. Put there IP addresses of your DNS servers but for that Site use as Primary DNS server for that Site Z ? and as Alternate DNS server other.

Reboot your client from that Site or run in command-line

ipconfig /release
ipconfig /renew
ipconfig /flushdns

ping OWA-Server

and verify if server replied with public IP address ?

Have you considered to set up Conditional Forwarders for that domain? I think its better that other options. Please read that MS article about Conditional Forwarding at

and MVP blog at

This will not apply in this scenario.  Conditional forwarders will not work.

The two AD sites have the name ABC.com as a local (internal) domain.  ABC.com is the external domain as well.

The mail server is on site 1.  Site 2 can not access MS Outlook OWA, but can access other servers in site 1 by going to the proper address (i.e. server.ABC.com)
