The meeting date range provides flexibility in determining when the meeting can be scheduled. Here are the options.
Number of days into the future: This governs how long your client can schedule the meeting. If you don't want your client to schedule a meeting six months from now, this option can help.
Within a date range: Specify a start and end date to set the active period for the meeting. Both the start and end dates are inclusive. This will ensure that your client can book a meeting only within the given date range.
Indefinitely into the future: This allows your clients to book a meeting way into the future. Be careful with this option.
As you change the meeting schedule options, you will observe the corresponding updates on the right side of the screen, where the calendar displays the active days.
