Note: This description describes a very simple scenario, later we will learn that in reality, the client protocol connectivity flow can be much more complicated and involved additional Exchange servers in the process.įinding the RPC Endpoint and multiple Active Directory sites When the Exchange CAS server accepts the Outlook client connection requests, he will look for information about the Exchange mailbox server which hosts the particular user mailbox (by query the Active Directory) and proxy the Outlook client requests to the Exchange mailbox server.In an Exchange environment, this “element” described as “RPC Endpoint”. The outlook looks for an “Exchange server” that can connect him to the mailbox.The standard “Outlook client protocol connectivity flow” is implemented in the following way: The infrastructure of Outlook client protocol connectivity flow Exchange 2013 CAS and Outlook legacy client.Outlook client protocol connectivity flow in an Exchange 2013 coexistence environment | The proxy process.Outlook client protocol connectivity flow before Exchange 2013 coexistence and after.Exchange CAS 2013 as a focal point for Outlook clients.The pre requirements changes that need to be implemented in the Exchange legacy environment.The evolution of Outlook communication protocols.The layer structure of the Outlook and Exchange communication channel.Exchange 2013, Outlook client and RPC over HTTP.The infrastructure of Outlook client protocol connectivity flow.
