I have follow this instructions https://exchangeserverpro.com/exchange-server-2010-cas-array to setup Exchange Servers.
Currently I have a CAS server:SerCAS, and it fqdn is outlook-cas.domain.local.
And I trying to create outlook profile by using MAPI, I am using the CAS server hostname:SerCAS but the function ConfigureMsgService failed. So I try the fqdn name:outlook-cas.domain.local, and it works.
Is that a way to query the fqdn from the hostname?
