Microsoft Bookings lets clients book appointments without contacting you first, but that convenience doesn’t always produce a schedule that works for you. Without the right restrictions, clients can book with too little notice, cancel shortly before a session, or choose times that leave no room between meetings. Fortunately, Bookings lets you adjust these rules so your calendar accommodates both your clients and the work you need to get done.
Global policies vs. per-service overrides
Bookings operates on two levels of scheduling policy. The global policies set on the Booking page apply to every service you offer unless you explicitly override them at the service level. This means your default lead time, cancellation window, and booking increments cascade down to all services automatically, which is efficient when most services share the same rules.
Microsoft Bookings lets you set general scheduling rules for all services and adjust them individually when needed. For example, you might require 24 hours’ notice for an initial consultation but three days for a premium service that needs additional preparation or equipment. Setting these rules at both levels helps you accommodate different service requirements without changing your overall scheduling policies.
Lead time: Controlling how far in advance clients must book
The lead time setting determines the minimum number of hours between when a client books an appointment and when that appointment can be scheduled. Microsoft specifies that the minimum is calculated against regular hours rather than business hours, so a lead time of 24 hours means 24 clock hours from the moment of booking, not 24 business hours.
For most appointment-based businesses, a lead time between 24 and 48 hours strikes a workable balance. It gives the business enough time to prepare for the appointment without turning away clients who genuinely need same-day or next-day availability. For services that require significant preparation, resource allocation, or coordination with other staff, longer lead times prevent the problem of an appointment appearing on the calendar with insufficient time to get ready for it.
Cancellation window: Protecting staff time
The cancellation window, also set through the lead time policy, specifies how much advance notice a client must give to cancel or reschedule an appointment without affecting the business’s ability to refill that slot. A cancellation made less than 24 hours before a service that needs preparation leaves less time to fill the vacant slot than a cancellation made a week in advance.
For services where a late cancellation cannot be filled and the staff time is effectively lost, a longer cancellation window is worth setting explicitly, either at the global level or as a service-level override. This creates a clear expectation for clients without requiring any manual enforcement: the system will inform clients of the cancellation policy during booking.
Time increments: Setting appointment intervals
The time increment setting controls the intervals at which appointments can start. A 15-minute increment allows an appointment to begin at 8:00, 8:15, 8:30, 8:45, and so on. A 60-minute increment means appointments only start on the hour. Shorter intervals give clients more flexibility and can help reduce gaps in your calendar, while longer intervals create more predictable scheduling blocks that are easier to plan around.
For businesses with tightly scheduled staff, 15- or 30-minute increments work well for most service types. For businesses where appointments begin at consistent, scheduled times (classes, group sessions, structured consultations), 60-minute or custom increments can prevent the fragmented calendar that results from appointments starting at irregular intervals throughout the day.
Buffer time: Protecting transitions
Buffer time can be added before or after appointments through the per-service settings in the Services section. Before-appointment buffers give staff preparation time; after-appointment buffers provide space for notes, cleanup, or a transition between back-to-back sessions. Neither type is visible to clients: from the client’s perspective, the buffer period appears as unavailable time, which prevents the next booking from starting immediately after one ends.
Buffer times are particularly valuable for services that require any kind of setup, documentation, or physical transition. A 15-minute buffer after each session gives staff time to complete follow-up tasks and prepare for the next appointment without having to block out time manually in their calendars.
Maximum advance booking window
The maximum days in advance setting determines how far ahead clients can book appointments. The default allows bookings up to 365 days in advance, which may be more than most businesses need. Clients who book months ahead may need to reschedule if their plans change, and staff availability may not be confirmed that far in advance.
Setting a practical limit, such as four to eight weeks for most appointment types, keeps the booking calendar manageable and reduces the need to reschedule appointments when client plans or staff availability change.
Staff availability and service-specific exceptions
Beyond the global scheduling policies, each staff member’s working hours determine when clients can book appointments with them. Microsoft Bookings only shows available times that fall within those hours. For services offered on specific days or by selected staff members, configure the relevant restrictions in the Services section so clients see only the appointment options that actually apply to them.
