Hello,

I believe if you create an appointment with just Subject, Start Date, End Date, and Time Zone then it is just an appointment.

But if you include a Required Attendees, then it becomes a meeting invitation and the invite is sent out to the Required Attendees.

However, you will likely have to also populate the body with the information to the meeting room, link, etc if applicable.

Hi @bsimon89 
Did these help solve your question? 

I’m hoping to get back to this topic this week and will update this thread when I do.  Appreciate the responses.
