Configuring Group Expansion

Dernière rubrique modifiée : 2009-02-27

When you install the Communications Server Web Components during setup of a Standard Edition server or an Enterprise pool, by default, group expansion is enabled for the Enterprise pool or Standard Edition server on which you install it. You can do the following to manage group expansion:

• Enable or disable support for group expansion.
• View the internal and external URLs that identify the location of the Web service that is used to enable distribution group expansion for internal clients and external clients.
• Change the maximum group size. The default maximum size of the group to which instant messages can be sent is 100. The maximum valid value is 1000.

To configure group expansion

1. Log on to the Web Conferencing Server using an account in the RTCUniversalServerAdmins group.

2. Open the Office Communications Server 2007 R2 snap-in.

3. In the console tree, expand the forest node, and then do one of the following:

   • For an Enterprise pool, expand Enterprise pools, right-click the pool, click Properties, and then click Web Component Properties.
   • For a Standard Edition server, expand Standard Edition servers, right-click the pool, click Properties, and then click Web Component Properties.

4. Click the Address Book tab.

5. On the Address Book tab, do the following:

   • To enable group expansion, select the Enable distribution groups expansion check box. If you enable group expansion, you can change the maximum number of users to which any instant message can be sent by typing the maximum group size you want to allow in Maximum group size.
   • To disable group expansion, clear the Enable distribution groups expansion check box.
