Coexistence Manager for Notes 3.9.1 - FBC Scenarios Guide

5-3: Configure DNS

You can use Network Load Balancing to permit multiple web servers to handle Autodiscover requests. This is optional, not required to deploy CMN. For more information, see this Microsoft article.

Configure DNS to point autodiscover.<smtpdomain.com> to the computer where CMN’s Autodiscover service is installed. For each domain, Exchange connects to predefined Autodiscover URLs using DNS host entries.

For Exchange to get free/busy information from the domain supported by a Domino server, through the CMN Free/Busy Connector, you must make the CMN Autodiscover Web Service resolvable to this URL:

On-premises Exchange or hybrid O365 using separate namespaces

Follow these steps, in order as presented here, to install and configure CMN’s Free/Busy Connector for on-premises Exchange or a hybrid Office 365 environment with separate (multiple) namespaces:

Remember that the FBC for a hybrid O365 is configured only between Notes/Domino and the local on-premises Exchange, while synchronization of the local Exchange to O365 is configured apart from CMN (and documented separately by Microsoft). Configuration of CMN’s FBC for a hybrid O365 is therefore the same as configuring for a local on-premises Exchange.

IMPORTANT: For a hybrid Office 365, remember to configure and test the hybrid connection between your local Exchange and O365, as documented by Microsoft, before configuring CMN’s FBC.

Step 1: Plan your FBC installation and configuration

To plan your overall FBC installation and configuration:

1-1: Verify system requirements

Review the system requirements (in the CMN Release Notes), and verify either that your environment conforms to the requirements, or that you will have the necessary hardware and software to meet the requirements.
