Once you have this configured, you can verify the connection using the tool netstat at the command prompt.
It should be fairly simple to configure the load balancer the vendor’s documentation should have details on how to do so.
If you cannot locate the Mail icon in Windows Control Panel, turn on. Assuming that the CAS servers are load balanced using NLB or HLB, Outlook connects to one of the CAS servers. Once configurations are made, the “Microsoft Exchange RPC” and “Microsoft Exchange Address Book” services should be restarted in order to apply changes. Go to your Outlook mail settings from Start > Control Panel > Mail > Show Profiles > Add. Active Directory hands back the autodiscover url and the Outlook client connects to the autodiscover service and gets the information for all the Exchange urls. Microsoft recommends setting this to a unique Registry value between 5954. If there are multiple AD sites, this Registry configuration has to be updated on all CAS servers in every AD site. Registry changes have to be made on all CAS servers in the Active Directory site. Outlook also uses other internal URLs from the XML file to access other services such as OAB, EWS, and the Availability service.Outlook uses these ports to establish a connection with the mailbox and address book.If the CAS server is configured with RPC and AB static ports, it will return the same otherwise, it returns anything between ports 600 for the RPC and AB services.Outlook requests the RPC and AB port numbers from the CAS server to access the mailbox and address book.Step 2: Search for Mail and click Mail (Microsoft Outlook 2016) (32-bit). Outlook uses the details in the XML file to talk to one of the Exchange 2010 CAS servers behind the load balancer and connect the RPC Endpoint mapper on port 135 of the CAS server. Step 1: Click Start and select Control Panel.Installation went good so far, however, users of Outlook 2016 are not able to connect to other user's calendars, although they can obtain access through OWA. This XML file will contain details such as the user’s display name, internal and external connection settings, location of the user’s mailbox, Outlook Anywhere settings, and the URLs of OOF, OAB, Availability service, and so on configured on the CAS servers. On our existing Exchange Server 2013 environment, we are starting to introduce Outlook 2016 (on W10 Pro). When Outlook starts, it talks to the Autodiscover service and requests a configuration XML file.Let’s see how the Outlook client accesses a mailbox using these static ports. See the Microsoft TechNet article for steps for configuring static ports for RPC and AB on a CAS server.
