You can initiate a meeting in two ways: on demand or via invitation. When you are in an instant message with someone, you can easily turn that instant message into a meeting by sharing and/or adding audio or video conferencing.
For more details, see the #6 Presentation button section earlier in this chapter.
You can also set up a meeting in a more formal way by sending an invitation. For more details, see the Sending a meeting invite section next.
