Can I schedule overlapping webinars?
Yes, but you can't host them both at the same time. It is possible to schedule more than one webinar for the same time slot, but you can only host one webinar at a time.
You will see a message warning you about the conflict when you attempt to schedule webinar that overlap, and you also will not be able to launch a new webinar until you end your last one. However, if you're already in a webinar and need to leave without ending it for everyone, you can promote any attendee in that webinar to be organizer so the session can continue on without you while you switch to the next one.
If your organization needs to host multiple sessions at the same time, then you can upgrade your plan to add additional organizer seats (these individuals would each get their own account with which they can schedule and host their own webinars).
If you attempt to run more than 1 webinar at a time, you will see a "Another Session Running" notification with an option to end the other session and begin yours. To continue, click End Other Session.
The organizer running the other session will receive a "The meeting has ended" notification.
