NoteNote:
1 If the number of participants in a Skype for Business meeting exceeds 75 participants, then the participant list (presenters and attendees) in the meeting roster will be truncated so that an individual attendee sees only the presenters and the individual attendee’s own name. The full participant list remains visible to the presenters in the meeting. Also, Gallery View and IM errors are hidden from the attendees.
