Outlook 2016 oab not updating in cached mode
Note that when configuring the Internal Host Name you also need to set the Internal Clients Require SSL option as well.To keep this example simple I am not requiring SSL for internal clients.The mailbox databases are currently active on E15MB2.
A much better user experience than before the Outlook Anywhere namespace was configured on the Client Access servers.
We also need to make sure that the DNS records exist for that namespace and resolve to the Client Access servers.
With no load balancer available to me at this stage I am using DNS round robin, which is not as good as proper load balancing but will do the job for now.
At the moment each of the servers is configured with their own name as the internal host name for Outlook Anywhere, which is the default.
