1. Once you have selected the recipients for your meeting, there is a nifty little button on the upper left hand of your meeting invite entitled “Scheduling Assistant,” click that.
2. Regardless of your permissions to the recipient’s calendar, the “Scheduling Assistant” will provide you with an overview of all recipients’ calendars
You will be able to adjust the time slot to see what time frame works the best for all of your attendees. The solid bars indicate that the recipient is already busy during that time period. The open spaces indicate that the recipient has nothing scheduled during that time period.
