On a computer that's running Windows 8.1 or Windows Server 2012 R2, Lync 2013 or Skype for Business 2015 users are intermittently unable to see the presence status of their contacts. Instead of seeing the correct contact status, the Updating status is displayed for most of their contacts. However when the user double-clicks a contact, a chat session is initiated when the contact is signed in.
This problem occurs because of a known issue in the Secure Sockets Layer (SSL) fallback that may cause connections to fail when SSL Version 3 is disabled.
