Microsoft is making some changes to Skype for Business Online Audio Conferencing Dial Out. To best meet our customer’s business needs, Microsoft is adjusting when attendees can add other participants to a Skype for Business meeting via dial out.
How does this affect us? Till now, meeting guests are able to add Audio Conferencing attendees at any time.
Going forward, the meeting service will require at least one authenticated user from the organizer’s company to be present in the meeting to allow adding another participant via dial-out.
