Hi
We are currently coexisting exchange 2007 and 2013 servers. Everything works fine, except OWA from the external.
Our domain is limocar.int.
Exchange 2007: exch2007
Exchange 2013: exch2013
On our internal DNS server, I've created legacy.limocar.int pointing to exch2007's IP address.
Exch2013 internal OWA: https://exch2013.limocar.int/owa
Exch2013 external OWA: https://mail.ourcompany.com/owa (where "ourcompany" is our company name)
EXCH2007 internal OWA was set to $NULL
EXCH2007 external OWA: https://legacy.limocar.int/owa
From the outside, I can log any 2013 users. But when I try to log a 2007 user, it changes the browser url to legacy.limocar.int, which indeed gives an error "The page cannot be displayed"
What am I doing wrong? instead of using legacy.limocar.int, should I use legacy.ourcompany.com? If so I will ask our public DNS to create legacy.ourcompany.com
Thanks for your help,
Martin
