While the new offline address book (OAB) created in an earlier lesson was distributed through public folders, the default offline address book is setup a little differently. The reason is because we indicated during the installation process we only had Outlook 2007 clients. Doing this means that the default offline address book will be distributed through the Internet Information Services (IIS). To verify that, you can click on the “Distribution” tab where you will find “Enable Web-based distribution” option enabled with its corresponding virtual directory listed.
Should you want to enable secure sockets layer (SSL) for greater security, you will need to do that from the IIS manager. Click on the Windows Start menu, go to “Administrative Tools” and click on the “Internet Information Services (IIS) Manager” link there. This will bring up the Internet Information Services (IIS) Manager where you can proceed to look for the OAB under the “Default Web site” node.
Select the OAB entry, and scroll down to look for the “SSL Settings” option at the bottom. Clicking on it will bring up a dialog with a “Require SSL” option, which also comes with the option to opt for 128-bit SSL. It is possible also to ignore, accept or require client certificates. When done, click on “Apply” to save the settings.
