Use the Distribution tab to specify the client support and offline address book (OAB) distribution points for the OAB.

Client Support

Select the version of the OAB that will be generated for the version of Microsoft Outlook that is used by your Exchange organization. If you have more than one version of Outlook in your organization, you can select more than one of the following versions:

  • Outlook 98 or later (Version 2)

  • Outlook 2003 or later (Version 3)

  • Outlook 2003 SP2 or later (Version 4)

If you do not select one of the Client Support options, the Office Outlook 2007 version will be generated.

Distribution Points

OAB distribution is the method by which the OAB can be accessed by users when they are working remotely or over a dial-up connection. To distribute the OAB, administrators can use Web-based distribution, public folder distribution, or both. An OAB distribution point is the HTTP Web address or public folder where client computers can download an OAB.

You can select one or both of the following check boxes:

  • Enable Web-based distribution   Select this check box to enable Web-based distribution. Web-based distribution is the distribution method by which Outlook 2007 clients that are working offline or through a dial-up connection access the OAB. With Web-based distribution, a Client Access server will contain an OAB virtual directory for Web distribution purposes.

    Click Add to specify the virtual directory or directories from which you want to distribute the OAB.

    Click Remove to remove the selected virtual directory from the OAB.

  • Enable public folder distribution   Select this check box to enable public folder distribution. Public folder distribution is the distribution method by which clients running Outlook 2003 or earlier that are working offline or through a dial-up connection access the OAB.
