Outlook & Calendly Not Synching

My Outlook is not linking with my Calendly. My Calendly was working perfectly until about 1.5 weeks ago. I had not changed my settings at all.

 

When I block off a few times on my Outlook, it does not block off the times in my Calendly. Based on the “Integration & Apps” tab on Calendly, my Outlook is indeed connected to my Calendly. I even removed my Outlook from the Calendar Settings subtab within the “Availability” tab and added my Outlook calendar back in but nothing has changed.

Hi ​@Christina40847 - Thanks for reaching out!

In this case, I would check two things to start:

  1. Are the events in your calendar marked as Busy? If they are marked as Free, Calendly will ignore those events.
  2. Are the correct Sub-calendars selected on the connections page? You can check this by going here, and selecting the dropdown: https://calendly.com/app/availability/calendar_settings

Let me know!

Thank you.

Hi David,

Yes, the events in my calendar are marked as Busy. No, my sub-calendar is not showing the correct one on the connections page. I don’t know how to fix it.

Got it, thanks for checking!

For context, Calendly will display the first 10 subcalendars that Microsoft sends us in the check for conflicts and add to calendar sections (please see below):

If you have more than 10 shared/sub-calendars, that may be why you are not seeing your preferred calendar(s).

Are you able to temporarily remove some of the calendars you currently have subscribed to see if that switches which calendars display in Calendly? You may need to disconnect + reconnect your calendar from your Calendar Connections page to update the display. Alternatively, some instances of O365/Outlook calendars will allow you to drag and drop your calendar list to rearrange it.

 

Could you give this a try from your calendar, then refresh your connection within Calendly on the Calendar Connections page?

 

Let me know! Thank you.

Ah, thank you. I temporarily removed a couple calendars from my Outlook and that did the trick. Thank you!
