The Office Communications Server back-end database stores user information. When you specify the maximum number of contacts to which each user can subscribe, consider the storage and performance impacts to your back-end database.

To specify the maximum number of contacts per user

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

  2. 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 Front End Properties.

    • For a Standard Edition server, expand Standard Edition servers, right-click the pool, click Properties, and then click Front End Properties.

  3. On the Generaltab, in Maximum contacts per user, type the maximum number of pool contacts per user for the selected pool.
