You can use Network Load Balancing to permit multiple web servers to handle Autodiscover requests. This is optional, not required to deploy CMG. For more information, see .
Configure DNS to point autodiscover.<smtpdomain.com> to the computer where CMG’s Autodiscover service is installed. For each domain, Exchange connects to predefined Autodiscover URLs using DNS host entries.
This procedure begins with the assumption that you have already reviewed the introductory chapter of this FBC Configuration Guide to . This chapter explains how to configure the FBC and the coexisting environments for F/B scenario #8, specified above.
Remember that the FBC for a hybrid O365 is configured only between GroupWise and the local on-premises Exchange, while synchronization of the local Exchange to O365 is a connection apart from CMG and documented separately by Microsoft. Configuring CMG’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 CMG’s FBC.
Review the System Requirements (in the CMG 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.
Scan through the installation and configuration procedures in this chapter, and think through what this process will entail in your own environment, to accommodate your own needs and preferences. Identify any special circumstances or issues, and determine how these will be addressed.
For any given scenario and configuration, it is possible to install all CMG F/B Connector components on a single server, as shown in the illustrations in the introductory chapter () of this Guide. However, many production environments experience sufficient query volume to warrant separate servers to ensure optimal performance. The instructions here therefore describe how to install CMG’s F/B Connector on two servers. If you prefer that all subcomponents reside on a single server, simply combine the components of CMG Server 1 and CMG Server 2 as they are listed below. All CMG Free/Busy Connector subcomponents are installed by the AutoRun utility included in the CMG product kit, as described in a later step in this chapter.
For Exchange queries for GroupWise F/B information, the simplest approach is to dedicate a separate CMG FBC Server 2 (as noted just above, for Exchange queries to GroupWise, and GroupWise replies) for each GroupWise server, with all the CMG servers feeding into the single Exchange server.
It is technically possible, but somewhat more complicated, to configure a single instance of the GroupWise FBC Service, EWS and Autodiscover to process free/busy traffic to and from multiple GroupWise servers—an approach that requires more elaborate GroupWise configurations.
Use the worksheet in Appendix A of this FBC Configuration Guide to gather and organize the information you will need to enter into CMG’s Management Console application when configuring the Free/Busy Connector. You can print the worksheet to paper, and use a pen or pencil to write the information into the wide right margins.
FBC coexistence with any supported GroupWise version requires the GroupWise SOAP web service, enabled on the GroupWise Post Office where the CMG service account resides. To enable and configure SOAP, see , and too.
