# Appointment availability

> Troubleshoot missing booking slots and notification setup problems.

If customers cannot find expected appointment times, review the appointment type from the top down.

## No slots are available

Check:

* The appointment type has at least one active advisor.
* The weekly schedule has enabled days and time windows.
* The appointment duration fits inside the available windows.
* Buffers do not consume the full window.
* Minimum notice is not pushing availability too far out.
* Maximum advance days is not too short.
* Time-slot interval is not hiding expected times.
* The workspace timezone is correct.

## Wrong timezone

Workspace timezone is configured in **Settings → Workspace → Regional & formatting**. Appointment type availability uses the workspace timezone.

## Reminder calls or SMS are unavailable

Check:

* A phone number is reserved for appointment reminders.
* The appointment type notification tab has that phone number selected.
* The notification type is enabled.

## Email notifications are unavailable

Check:

* A verified email domain is selected.
* A from address is set.
* The notification email toggle is enabled.
