KB2739693 which will tell you that presence unknown may occur, if you apply the Update 2571543 or later CU for Lync 2010 client.

Case 3:

Out-of-Date Outlook Contacts

This issue has been around for awhile but can become more noticeable over time.

When a Lync 2013 user searches for a contact in the Search Contact box, the contact will show an incorrect Presence state. 

he resolution is simple enough – delete the SIP profile directory and restart the client. The SIP profile folder is located here:

> %UserProfile%\AppData\Local\Microsoft\Office\15.0\Lync

Note – I achieved the same results just deleting the local address book files (GalContacts.db and GalContacts.db.idx) but you should delete the whole folder to be safe.

As the Next Hop article points out, deleting this SIP profile folder will trigger a complete address book download at a random interval in the next hour from when the client is restarted.  A user can tell if the address book is completely downloaded when the “Address book synchronizing” status goes away when searching for a contact
