Common Errors
The three most common errors our users see.
This error occurs when a date/time conflicts with a busy event in your connected calendar. The "details" dropdown in troubleshooting mode will show the connected calendar where the event is present.
Recommended Steps to Resolve:
- Review calendars & sub-calendars within your checked for conflicts section in Calendar Connections.
- Ensure any all-day events on your personal calendar/sub-calendars for that date/time are set to free.
Articles below share examples of busy events depending on calendar type.
- Google Calendar
- Outlook/Office 365 Calendar
- Outlook Plug-In Calendar
- Exchange Calendar
- iCloud.com Calendar
Important note: There is no way to override busy events on your connected calendar. Because Calendly sees each account as an individual user, it does not allow for overlapping events.
Because Calendly sees each account as an individual user, it does not allow for overlapping Calendly events to help prevent double bookings.
Event Settings Errors
These errors occur when there is an issue with your Event Settings.
This error appears when a date/time interferes with a buffer on a scheduled Calendly event.
IMPORTANT: Event settings lock in when an event is scheduled. Removing the buffer from the event type will not remove it from an event that has already been scheduled.
To remove a buffer from an already scheduled event, you can review this article for steps on how to do so.



1. Change your event duration from within your event settings.
OR
2. Adjust your availability to ensure the event duration will fit.
For example: You have an event that is 2 hours long, but only have availability from 9am-10am (one hour). There would not be enough time available for a 2 hour long event to take place.
To update your date range, review your event types settings and edit the date range section.
NOTE: To add Saturdays & Sundays to your availability, assign weekdays and not business days to your event.
Event Type Errors
The errors below are event type specific errors.
This error occurs with Group Event Types. This error appears when a Group event has reached its maximum number of attendees.
Important note:
Event Settings lock in at the time of booking. Changing the max number of invitees will not change events that have been booked. To change max invitees for an event that has already been scheduled, you can do so from the scheduled events tab.
For collective events, a date/time will only appear when all hosts assigned to that event are available.
For these dates/times to appear, ensure that each member's scheduled meeting total is equal to (or only 3 meetings ahead) of other members.
Less Common Errors
Errors that are less common but still occur.
This error occurs when Calendly is unable to connect to your calendar or a team members calendar. Ensure all calendars are connected in the Calendar Connections page for your/your teams accounts.
Clear reserved times by visiting the pending section in your Scheduled Events tab. Then select Clear reserved times.
NOTE: Delays can occur when removing reserved times from your connected calendar.
