Hi there, I am in the middle of upgrading our Mac environment to Lync 2011 14.0.7 with Hotfix (140123) however, I'm having some difficulties with our Lync clients not being able to perform searches of users using the friendly name of the user. Searching only appears to work if a full e-mail address is specified.

I checked my sip_username@domain.com which is created in Documents\Microsoft User Data\Microsoft Lync Data\ and my account is missing the GalContacts.db, GalContacts.db.idx and GalContactsDelta.db. This is a fresh install and it was working on my machine prior to the fresh reinstall of the OS and applications. I am currently running Lync 2011 14.0.7 (140123) on Mavericks 10.9.2.

I have checked 14.0.6 on a fresh Mavericks 10.9.2 machine as well, with the same account it does not function properly. I asked another user to check their upgraded Mavericks install with Lync 14.0.5 and he is able to put a user's first or last name into the search field and search data will get returned, so I know that if there is an existing GALContacts.db results will be returned but any new installs never have this offline address book cache created and I'm afraid that existing offline address books contain data that is only as current as the last pull before migrating a user to Mavericks.

Is there an issue with Lync 2011 on Mavericks? Is there a fix or work around that is available?

Lync Server 2013 supports the following clients on computers that are running Mac OS 10.5.8 or latest service pack or release (Intel-based) operating systems (Mac OS 10.9 operating system is not currently supported).
