Next, select the option Connect your calendar. Choose the calendar program that corresponds to your Email: Google Calendar or Outlook 365. To check if your email provider is compatible with Meetings, refer to this article.
Finally, when prompted, select Allow in order to give Meetings access to your calendar.

This helps prevent double bookings from occurring, and you never need to bother with let a prospect know the windows of time you are free!
