Windows 10: Windows 10 Calendar not syncing all icloud calendars

My iCloud calendars used to show up in the Calendar app, but now only one does. I have a few icloud calendars, one of which is a shared calendar with my partner and until last week all calendars were visible in the Calendar app on my desktop, but now only one is, not the shared calendar.


I tried deleting and re-adding the account. Updating windows. Restarting my computer etc. If I add an event to the shared calendar on the desktop it shows up for a second then vanishes, but is in the calendar on my phone.


Can't seem to get this sorted and it's really frustrating!

Problems syncing iCloud Calendar with Windows 10 Calendar

Hi Rick,



Thank you for posting your query in Microsoft Community. I regret the inconvenience caused to you. Let me help you.



I suggest you to go through the below steps and check if it helps.

• 
  Login to your Apple ID and password.
  
• 
  Choose ‘Calendar‘, click on the ‘WiFi’-like Logo next to the calendar you want to see in Windows 10 calendar app.
  
• 
  Choose ‘Public Calendar‘ and send copy the link.
  
• 
  Next, login to your outlook.com account, go to ‘Calendar‘ in the PC website view, click on ‘Import‘, then on ‘Subscribe‘, choose a calendar name, paste the iCloud calendar link
  and click ‘Subscribe‘.
  
• 
  Now the iCloud calendar subscription is processing and after a short while you can see your iCloud calendar apps on outlook.com.
  
• 
  For checking correct syncing, go to the settings wheel on the right upper corner, click on ‘Options‘ and then on the name of the iCloud calendar subscription you gave in step 4. Under ‘Last Refresh‘,
  you can see the refresh period and the number of correctly synced events.
  
• 
  Open Windows 10 calendar app. If you’ve already set up your outlook.com account, you will see the iCloud calendar subscription in ‘read-only’ mode.

How to enable Calendar sync with microsoft? (Windows 10)

Read the article How To Sync iCloud Calendar With Windows 10 Calendar App.

It explains why the sync doesn't work and describes a workaround for syncing iCloud calendar with Windows 10 calendar app, but with the restriction of ‘read-only’ calendar syncing.

If that's not enough for you, you will need to wait for Microsoft to improve
the implementation of its CalDAV and CardDAV protocols for calendar.
As they are already working for Mail, it is probably just a bug that should
be solved soon enough, since the problem was already signaled to Microsoft.
