The property values for the MSFT_SIPIMMCUSetting class map to the settings found on the IM Conferencing tab of the Front End Server Properties dialog box. You can access these values in the Office Communications Server 2007 R2 Administration Tool by right-clicking the name of a front end server, pointing to Properties, and then clicking Front End Properties. (For an Enterprise Edition server, click Properties rather than Front End Properties.) In the Front End Server Properties dialog box, click the IM Conferencing tab. Note that these settings apply only to the specified server.

The following syntax is simplified from Managed Object Format (MOF) code and includes all inherited properties. Properties are listed in alphabetic order, not MOF order.
