If you are still using Office Live Meeting – the first Microsoft online meeting service, precursor of Skype for Business Meeting Broadcast – you need to start thinking of moving to a newer solution like Skype for Business or Skype for Business Meeting Broadcast as the service is going to be shutdown on December 31, 2017.

Existing OLM meetings will continue to work until the final shutdown; so start using the newer services.
