This topic explains how to use the Exchange Management Console or the Exchange Management Shell to modify the settings of an offline address book (OAB) virtual directory. The OAB virtual directory is the distribution point that is used by the Web-based distribution method of the OAB. By default, when Microsoft Exchange Server 2007 is installed, a new virtual directory named OAB is created in the default Web site in Internet Information Services (IIS). You can then modify the OAB distribution point settings to meet the needs of your organization.

Before You Begin

To perform the following procedure, the account you use must be delegated the following:

  • Exchange Organization Administrator role

For more information about permissions, delegating roles, and the rights that are required to administer Exchange 2007, see Permission Considerations.

Procedure

To use the Exchange Management Console to modify the settings of an OAB virtual directory

  1. Start the Exchange Management Console.

  2. In the console tree, expand Server Configuration, and then click Client Access.

  3. In the work pane, on the Offline Address Book Distribution tab, click the distribution point you want.

  4. In the action pane, under the name of the OAB, click Properties.

  5. In <OAB Name> Properties, on the General tab, you can modify only the polling interval. In the Polling interval (minutes) box, enter the frequency (in minutes) that you want the distribution point to check for updated OAB files. An interval of 0 means that the distribution point will not poll. The default is 8 hours (480 minutes)

  6. On the URLs tab, you can modify the following settings:

    • Internal URL   Use this box to enter the URL that users on the corporate network can use to download OAB updates.

    • External URL   Use this box to enter the URL that users can use to download OAB updates from the Internet.

      Note:
      Although Web-based distribution is enabled by default and does not require further configuration, we recommend that you enable Secure Sockets Layer (SSL) for the OAB distribution point. For more information, see How to Require SSL for Offline Address Book Distribution.

  7. Click OK to close <OAB Name> Properties.

To use the Exchange Management Shell to modify the settings of an OAB virtual directory

  • To change the internal URL, external URL, and the interval (in minutes) at which the distribution point will poll for an updated OAB, run the following command:

    Copy Code 
    Set-OABVirtualDirectory -Identity "OAB (Default Web Site)" -PollInterval 120 -InternalURL "http://contoso/oab" -ExternalURL "https://www.contoso.com/OAB"

For detailed syntax and parameter information, see Set-OABVirtualDirectory.
