Hi guys,
we have UTMs in our 3 main sites - North America, Europe and Asia.
Each of these 3 main sites have 2 Exchange 2013 Servers.
Both internal and external users connect using the Outlook Anywhere hostname.
For each site we have one like na.domain.com, eu.domain.com and as.domain.com
So let's assume the Sophos UTM in North America goes down, how can I accomplish a failover so clients will be able to continue working.
(Assuming we have database copies on all Exchange servers)
Many thanks!
