Include support for iCloud Calendar.
Adding a contact in Outlook should not only add it to the proprietory "People" section but also to the native Mac contact application. This can also be done with calendars when using iCloud accounts.
The contacts and calendars are handled in an outdated fashion as they are not integrated into core MacOS apps. Other apps such as Spark do this in the correct way, contacts and calendars are synced with system apps.
I fully agree with the other comments - the same goes exactly for me. I see that it is planned now, and that is great news! I really hope the wait will be over soon (as yes, I have been waiting for this for years).
Either sync with Apple Contacts or provide direct access to them from within Outlook

This is a huge problem for me as I have 3 work calendars on outlook and 2 personal calendars, one shared with my family, on my/their iCloud accounts. Without an iCloud solution I can't use outlook on its own, which is very annoying.

Until outlook supports this, it will never be the one solution for my calendar. It will always be secondary since it does not show my whole agenda.

I'm a Mac user primarily (I used Parallels) I love Outlook but I really think it's about time you provided for sync with iCloud. Thanks
