Our Exchange DAG environment is spread over two sites. We have a site in Sydney and another in Melbourne.
Sydney is our main office whereas all Exchange Databases are mounted.
Melbourne is used as a disaster recover site when Sydney is ever to go offline.
Melbourne and Sydney are connected over the WAN and both have separate external IP addresses.
mail.mycompany.com external DNS record points to Sydney
mail-r.mycompany external DNS record points to Melbourne
OWA, Smart Phone devices etc are configured to connect to Sydney at mail.mycompany.com
Is it possible to configure Exchange so that if/when Exchange databases failover to Melbourne in DR then ActiveSync will still be available on iPhone and Android devices?
Thanks for your help
