I have introduced a 2010 exchange server to my exchange 2007 environment and am working to get them to coexist.
I have ONLY 1 exchange 2007 server with all roles installed on it for email to function properly. I have introduced a new exchange 2010 server and it will be setup the same exact way with all roles installed on ONLY itself for email to function properly.
I have successfully moved the OAB, Public Folders and 1 test mailbox to the new exchange 2010 server and now need to setup OWA and autodiscover to be reachable externally.
right now it works internally properly!
Meaning that if i open a browser inside the network and goto to the internal FQDN (https://mail.mydomain.com/owa
) for the new 2010 exchange server and try to log in as a mailbox user on the exchange 2010 server it will open their mailbox and if I login as a user whos mailbox is NOT on the exchange 2010 server (and the mailbox resides on the exchange 2007 server) it will redirect me to the exchange 2007 OWA site and i can log in with no problems and see mail.
Now according to this article I need to somehow swap the DNS names and change the name of my existing exchange server:
can someone be a little more clear about what i need to do in my particular case?
Here is my current setup info:
exchange 2007 FQDN server name: exchange07.mysubdomain.myd
external 2007 OWA address: https://exchange07.mydomain.com/owa
new exchange 2010 FQDN server name: mail.mysubdomain.mydomain.
What i would like my external address to be for this: https://mail.mydomain.com/owa
Please note that i am currently redirected to exchange 2007 OWA site when I enter the address above externally (https://mail.mydomain.com/owa
) but i am unable to login to the test mailbox that i have moved to the exchange 2010 server - it basically shows this page when i try to log in:
I am however able to log in externally to that address above (https://mail.mydomain.com/owa
) for a mailbox that resides on the exchange 2007 server with no problems. I find this strange as I have always given out https://exchange07.mydomain.com/owa
For OWA access info....
So does this mean there is an existing redundant A record in my external DNS that is going to my exchange 2007 server?
