None of the Communicator for Mac 2011 clients in our organization are downloading the address book from OCS 2007 R2. Windows Communicator clients are getting the address book without issue and no address book generation errors are appearing on the OCS server.
Windows and Mac clients are both finding OCS resources via DNS and the Mac clients can sign-in without issue. I've tried enabling logging on the Mac Communicator client, but the resulting log file is huge and I didn't find any smoking guns anyway.
Any suggestions as to how to troubleshoot this issue?
Thanks,
Andy
