Have a site that has two internet pipes. Currently their email goes offsite to our facility to be scrubbed for spam and then goes to their site. The MX record points to us and then after the email is scrubbed it hits the site. This part is not hard for me to failover.
The trouble I am having is I want to failover OWA when the main internet pipe goes down. Currently we have an A record pointing to their server for OWA. This resolves to one of the internet pipes. When that pipe goes down they lose OWA. How can I resolve this?
Thanks!
