Description

When joining a Skype meeting from the Outlook or Skype calendar, the video for the active speaker shows a blue screen.

The issue is not seen by attempting the following:

  • If you join by pasting the Skype meeting URL into a web browser or launching from Outlook Web Mail it works.
  • This works fine for peer to peer video calls and if a user starts an ad-hoc conference call and adds the participant manually.

Environment

  •      Receiver version:  4.4.1000
  •      HDX Connector/RTME:  2.1.0.602
  •      Skype Client: 15.0.4833.1000
