In a few cases, I've seen where the Lync 2010 back-end databases seem to get "stuck" in "Restricted User" mode. When the databases get thrown into "Restricted User" mode, the database becomes inaccessible and therefore many of the Lync features become unavailable. In my experience, this usually occurs during a failed run of the database update required for Lync Cumulative Updates (CU). As part of the update, it is important to stop the Lync services using the Stop-CsWindowsService cmdlet on the Front End where you are running the database update command. In environments with larger pools, it is also a good idea to stop Front End services on all servers in the pool, as I have seen "deadlocks" and other strange issues when updating the Lync back-end while multiple servers continue to access it.
