Microsoft Communicator error ” Cannot Synchronize Address Book “

A common issue we see is clients getting an error stating “Cannot Synchronize Address Book”.  It looks like this:

This is an action that the OCS installation doesn’t take care of automatically so it happens pretty regularly.  To resolve it, select the Directory Security tab and click on the Server Certificate Button

After you click on the Server Certificate button, follow the Wizard, select Assign an Existing Certificate and assign the certificate used by your OCS Server for client logins.  Once you’ve assigned the certificate the SSL port on the Web Site tab should be filled in with port 443.

Sign your clients out of Communicator and then back in and the Address Book should be downloaded successfully
