Microsoft has released the server update for Lync Server 2010 following their previous client CU2 updates a few weeks back. The server updates have once again been combined into a nifty update package LyncServerUpdateInstaller.exe which figures out what needs to be installed and in what order on each server. It can also be run to verify what patches have been installed. Of course individual updates still exist as well if you prefer to patch in that manner (but why?) and they can all be found here.

Microsoft has completed their testing of SQL Server 2008 R2 and Lync Server 2010 and has found the database to be compatible. This is great news for companies that have an existing SQl 2008 R2 environment and have had to in the past setup a new SQL server/cluster just for Lync Server. The official blog from Microsoft may be found here.
