# Troubleshoot appointment availability and time zones in Infinity3

Use these checks when expected slots are missing, busy periods remain bookable or times look incorrect.

#### Before you start

Have the booking link, affected date and intended team member ready. Record the timezone displayed on the booking page.

#### Check an unavailable slot

1. Open the booking calendar’s settings.
2. Review the relevant user’s working hours and date-specific availability.
3. Check booking notice, scheduling range, buffers, duration and capacity where applicable.
4. Review existing appointments and selected conflict calendars.
5. Use **Troubleshoot Calendar** where available to inspect the affected date and time.

For a team calendar, check which members are eligible for the booking rather than assuming one person’s availability determines the result.

#### Check a busy time that remains bookable

Confirm the external account is connected, the correct conflict calendar is selected and the external event is marked busy. Review any sync warning and allow the update to complete before retesting.

#### Check a time difference

Compare the calendar, user profile, external calendar and booking-page timezone. Different zones can show different clock times for the same appointment.

Use a named regional timezone where available and check dates around daylight-saving changes.

#### Things to know

- Test the public booking link as well as the internal calendar view.
- Do not remove genuine commitments merely to make slots appear.
- Keep a note of settings before changing them.
