How to connect your Office 365 or Outlook.com calendar

Connect your Office 365 or Outlook.com Calendar to Calendly for seamless scheduling. Prevent double-booking and automatically add new events for better time management.

Connect your calendar upon signup

When you sign up for Calendly using your Office 365 or Outlook.com email address, your calendar will automatically connect to your account. You can visit your Calendar settings page to confirm or customize your calendar settings.

How to connect your Office 365 or Outlook.com calendar

Step 1 – Visit your Calendar settings page

1. On your home page, go to the left-side navigation panel and select Availability.
2. At the top of the page, select Calendar settings.
   

Step 2 – Select the calendar you'd like to connect

• If you haven't connected a calendar yet:
  • Next to Outlook Calendar, select Connect.
    
    
• If you've already connected a calendar:
  • You can add additional calendar accounts by selecting + Connect Calendar Account.
    
    

You'll be prompted to sign in to your Microsoft Office 365 or Outlook.com account. Once authenticated, you'll be redirected back to the Calendar settings page.

Step 3 – Edit your calendar(s)

If there are multiple calendars on your Outlook account, choose which you would like Calendly to check and add new events to. 

1. Choose which calendar(s) you'd like Calendly to check for conflicts:
   
   Select 'checking x calendar(s)' in the Calendars to check for conflicts section.
   
2. Select the calendars you would like Calendly to check for conflicts.
   
   Notes:
   • You can select up to 4 sub-calendars to check for conflicts.
     
   • If you have more than 10 sub-calendars, note that Calendly will display the first 10 sub-calendars that Microsoft sends us.
   • Calendly can only connect to calendars that you have permission to edit. If you have read-only access to an Office 365 calendar, Calendly cannot connect to it. For more details, view Microsoft's Share an Outlook Calendar with other people.
     
     
3. Choose when Calendly shows you as unavailable:
   
   In the Calendars to check for conflicts section, under the What's considered unavailable? dropdown , you can choose how you'd like Calendly to read the availability statuses you set in your calendar. 
   
   
   
4. Choose which calendar you'd like Calendly to add new events to:
   In the Calendar to add events to section, select the calendar you would like your events added to.
   • Here, you can enable Sync Cancellations. When turned on, any Calendly event you decline or delete from this calendar will be canceled in Calendly. Note that changes made by invitees on their own calendars won’t affect the event status in Calendly.
     
     

How Calendly reads your Office 365/Outlook.com 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:

Usually, events in your calendar are marked as Busy to prevent double-booking. But you might want to change your status for out-of-office or holiday times.

By default, Calendly marks you as unavailable for events labeled as Busy, Working Elsewhere, or Away, so these times won’t show on your scheduling page.

If you want to be available during these statuses, you can uncheck the default settings by following step 3.2 above.

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:
