Cumulative update package (CU6) released for Lync 2010: June 2012

June 17th, 2012 | Tags:

The latest batch of Lync cumulative updates are detailed below, server-side updates can be deployed via the Cumulative Update installer (recommended) or manually (via this page). Updates will as always make their way to Microsoft Update.

Some new features worth mentioning:

  • The ability to switch user when Aries phones are configured as common area phones for hotdesking and locked by another user
  • Aries will support wildcard certificates (for Exchange and Lync), this increases the opportunity of running wildcard certificates within a Lync 2010 environment. There are still some limitations of course, such as backward compatibility with LCS/OCS etc. Jeff Schertz, a fellow Lync MVP has written a great post on this (disregard the last gotcha on Lync Phone Edition clients)
  • The ability to view uploaded Microsoft PowerPoint presentations within a scheduled Lync Meeting, as well as view the meeting participants’ list – more on this here

    Lync Phone Edition cannot sign into Microsoft Lync. All other client types can.


    Lync Server 2010 Multi-Tenant Pack. Using edition 4.0.7577.4051

    Front-End Server, Director and Edge Pools all use WildCard Certificate.

    Lync Phone edition Clients are using firmware version 4.0.7577.4100 which was release June 2012 and the release note states that wildcard certificates are now supported.


    SIP Stack Trace on Edge Pool:

    – “The connection was closed before TLS negotiation completed. Did the remote peer accept our certificate?”

    Reverting to Standard UC Cert from same Root CA ( allows the device to sign in. Therefore, the conclusion is that the device’s STILL do not support WildCard Certificates. Is this the case?
