How to troubleshoot unavailable times that should be available
Quick answer
If invitees are seeing times as unavailable when you expect to be free, here's how to check and fix it:
- Open the Troubleshoot tool on your live booking page or in preview, scroll down, and select Troubleshoot. Choose a date to see what's blocking each time.
- Check calendar conflicts — if you see a CALENDAR code, a connected calendar event marked as "Busy" is blocking that time. Update the event to "Free", remove it, or reconnect your calendar.
- Review event settings — codes like DAILY MAX, WEEKLY MAX, MONTLY MAX, RANGE, or TOO SOON mean booking limits, date ranges, minimum notice, or availability rules are preventing scheduling. Adjust these settings in the Event Type editor.
- Check other Calendly bookings — EVENT or OVERLAP codes mean another Calendly meeting is scheduled at that time. Reschedule the meeting or update your Free/busy rules if overlapping meetings are allowed.
- Look at buffers or holidays — BUFFER or HOLIDAY codes mean buffer time or a holiday setting is blocking that time. Update or remove those settings if needed.
If the Troubleshoot tool doesn't show a clear reason or you're unsure what a code means, review your connected calendars, availability rules, and calendar sync settings.

Calendar sync
These codes mean something in your connected calendar is blocking a time. You may need to change an event or reconnect your calendar.

CALENDAR | A "Busy" calendar event is blocking the time. | Change the event to "Free" or remove it from your connected calendar. |

Event Type settings
These codes come from your event’s rules. You might need to change limits, time ranges, or notice settings so invitees can book again.
Code | What it means | How to fix it |
DAILY MAX | You’ve hit the daily meeting limit for that event type. | Adjust limits under Limits and buffers in the event editor. |
DURATION | Not enough time for your event. | Shorten the event or extend your availability. |

Calendly meetings
These codes show that another Calendly meeting is blocking the time. You can fix this by rescheduling or adjusting meeting rules.

These codes appear for team events, like Collective or Round Robin. They tell you when a host isn’t available or when scheduling rules need an update.
