Here's how to use it:
1. Create a meeting.
2. Add meeting attendees.
3. Make sure the meeting time is Undecided (it is by default).
4. Add dates and times to the meeting scheduler (at the bottom of the page).
5. Save your meeting.
6. In the Overview page, you can see the scheduler. Send scheduling request to the attendees. Please note that only the attendees who are users in the specific meeting category will be listed/populated as recipients in the Send popup (because only your account users can log in and use the scheduler).
7. After all attendees have set the times suitable for them, the organizer can check which date and time is suitable to everyone.
