Apple and Microsoft OS were not friendly enough to synchronize iCloud calendars on Windows Operating system. Apple hesitates to break its echo system and limited real-time synchronization and other features in between MAC and iOS devices.

Apple released its application for Windows users to integrate iCloud features with Windows OS. Unfortunately, “iCloud for Windows” failed to give the same user experience that enjoyed by Mac users.

  1. Since my day 1 at work, I was taught to use OIutlook years ago. I think I will vote for Outlook over Windows 10 Mail app no matter what. One great thing about Windows’ built-in Mail app is the support of Google Calendar API & iCloud calendar, which is CalDAV! Yes, it is CalDAV. I give a big thumb for it. Now, I wonder why Outlook does not support Google Calendar API, CalDAV and CardDAV even till the most recent Outlook 2016. Sadly, Google Calendar Sync had been discontinued. Yet Apple’s iCloud Control Panel has issues of no way to assign iCloud folders as Outlook’s default folders. I turn out to use some Outlook add-in such as EVO Collaborator for Outlook to resolve this issue. Since this add-in synchronizes both Google Calendar, iCloud and more, I am kind of better off now. Till maybe when Microsoft comes out with a built-in CardDAV and CalDAV support, I will try it to see how it works.

  2. I have an iCloud calendar set up, sharing it with my wife. All of a sudden, the entries in the family calendar disappeared on my laptop. They’re still visible on my iPhone. I added a new calendar entry, and all family calendar entries re-appeared. What caused it?

    • we have the same problem. The iCloud calendars show up in the list of calendars on the PC, but none of the entries show up in the calendar. I can add an event from the PC side, but it disappear in a couple of seconds. It still shows up on all the other iCloud devices (iPhone, iPad, icloud.com, etc). But it does NOT show upon the PC calendar anymore. It seems lots of other people of related problems. This is on a brand new PC with nothing else installed, Windows 10.
