Managing the Use of Distribution Groups to Send Instant Messages

Communications Server 2007 R2

Topic Last Modified: 2009-02-27

In Office Communications Server 2007 R2, you can enable group expansion to allow users to send an instant message or a meeting invitation to a distribution group in Active Directory. Distribution group expansion enables users to invite all or selected members of a distribution group to an instant messaging (IM) conversation without having to search for and add each one individually. To do so, Office Communications Server 2007 R2 accesses an Internet Information Services (IIS) server that hosts the distribution group expansion service so that the group membership can be expanded to individual users to whom meeting invitations or instant messages are sent.
