      • If you don't select sync cancellations, any events you cancel on your calendar (and not through Calendly) will not show as canceled in Calendly. 
      • Sync cancellations only apply to you as a Calendly user. If an invitee deletes or declines an event on their calendar, the event will not show as canceled in Calendly.

How Calendly reads your Office 365/ calendar event status 

Within your Office 365 calendar, you can set your event status to Free, Working Elsewhere, Tentative, Busy, or Away/Out of office:


Most of the time, events are marked as Busy in your calendar so people cannot double book you. However, you may want to update your status when you're out of office or on holiday. 

By default, Calendly considers you as unavailable during events that are marked as BusyWorking Elsewhere, or Away, and those times will not show on your scheduling page.

However, if you would like to be considered available during these statuses, you can uncheck the default settings by following step 3.2 in How to connect your Office 365 of calendar.


Consent and admin approval

When connecting your calendar, you may encounter a message about requiring admin approval, permissions, or consent.


If you need approval, work with your IT admin to grant the relevant permissions in Microsoft. To learn more about consent in Azure Active Directory, view Microsoft's:
