NimbostratusWe've setup GTM as described and only for internal, external users need to VPN in for email. More detail on the cNAME; it's a cNAME on an A record in the internal.domain.com and the A record we chose was the IP address of the service VIP on the LTM in the primary data center. The cName data points to the wip.domain.com. Our GTM is setup for manual failover of exchange records, to prevent any false positives. The WIP has 2 pools and is setup for global availability. The pools are setup with an IPv4 fallback IP to ensure the pool always available until we manually disable it to initiate failover. As stated in previous thread, there are a TON more details and it will depend on your requirements. Hope this helps.

NimbostratusYes, we started with the goal of automating Exchange failover with GTM but was advised by MS to make this a manual process to avoid unintended failover. The 'win' from this is twofold; we have a centralized place to failover all our Exchange records and we know have GTM in the environment to support other applications. Build it and they will come mantra.
