Lync 2013 Client Update – April 2014

Hot on the heels of the oft-confusing March Client update (with its seemingly inconsistent version numbering), here’s a juicy April offering with lots of identified fixes. Conspicuous by its absence is any reverting of the emoticons to the animated, unambiguous & friendly pre-SP1 ones, but let’s not harp on about that.

This update takes us to 15.0.4605.1000.

What’s New / Fixed?

Did I mention the emoticons haven’t been reverted? If you feel strongly about this, pop over to the IdeaScale website and lend your support.

Known Issues

Updated 14th May: If you install this update, users of Outlook 2007 and and Outlook 2010 will no longer be able to see (or call) the numbers of their Outlook Contacts. Microsoft is aware of this and offers two work-arounds: edit the Contact to remove their e-mail address, or change the user’s CsClientPolicy to set “DisplayPhoto” to “NoPhoto”. Bounce the clients, wait for a contact re-fresh/re-synch and all will be well – just a bit clunky without the photos.
This has been fixed in the August 2014 update – at least for Outlook 2010.

After you install this update, you may experience the issues that are described in the following Microsoft Knowledge Base articles:

  • 2898357 Screen readers cannot read aloud keystrokes during a Lync 2013 application or desktop sharing session in Windows
  • 2932389 Persistent Chat file transfer fails between an external user and an internal user in Lync 2013
