Second/Backup OWA site for backup line

Dear All, I am in a bit of a challenge here finishing a secondary or backup OWA site for the backup line. We currently have MX records with a different priority for example webmail.xxx.org has priority of 10 and is bind to X public IP address. Our iphones are set to work with that and our OWA remote email access. All set here.

However, If the X IP address network goes down our email still works with a backup line with Y IP address. I need to know how or what to do for our Y public IP address to also answer or provide remote OWA solution so the user instead of going to webmail.xxx.org just change the address to webmail2.xxx.org.

I have the MX record for it, the connector in exchange 2007, The firewall already has the rule, I am wondering about the certificate and the IIS part.

Thank you!

you should have the same certiifcate install on this other cas server
you should configure your external dns A record for webmail with a short TTL
when you need to failover update the IP address
I assume that only your line / IP changes during an internet failover, not the back end of CAS and Mailbox servers.

In that case, the certificate should have the 2 names registered with it. webmail and webmail2. Also dont have to worry about IIS

Yes,the secondary line fails over. I have it so in an ASA 5505.


So am I going to have to "regenerate a certificate for both OWA" or should I buy a new one?
