Trying to define a solution for *outbound* load balancing from Exchange 2013 organisation between Edge Transport servers.
Setup:
1 Edge Transport server in SiteA
1 Edge Transport server ins SiteB
Both subscribed to the AD site in SiteA and are therefore on the same send connector (to allow automatic load balancing and failover)
Situation:
Lets say all MBX/CA servers in SiteA go offline. Can an MBX/CA server in SiteB send email directly to the Edge Transport that is subscribed to the AD site in SiteA, or does there need to be an MBX/CA server available in SiteA to hop through?
I'm hoping for an answer to be backed up clearly by a TechNet article or authoritative source as I can't really work with guesses.
Thanks.
Let’s say I have an Edge Transport subscribed to ADSiteA. All MBX/HT servers in ADSiteA go down. Can a MB/HT server in ADSiteB send an email directly to an Edge Transport subscribed to ADSiteA, or does it need to hop through an MBX/HT in the subscribed site?
