sync calendar/contacts with iCloud versus iTunes

I use iTunes on a Windows 10 PC to sync my Outlook 365 Calendar and Contacts with my iPhone 8 calendar and contacts. Today I received the following message in iTunes: "Support for syncing contacts and calendars has been deprecated and will be removed in a future version of iTunes."


I think it is still syncing. My questions are as follows:

  1. Best option if I cannot use iTunes - Is it iCloud?
  2. If it is iCloud - will it duplicate all entries the first time I use iCloud to sync or does it recognize the two (iPhone calendar/contacts & PC based Outlook calendar/contacts) are already synced and just add/remove/change any differences? I have not used iCloud in past.


One last note: I sync both an iPhone and iPad Air with my Windows 10 PC.

Windows, Windows 10

I’ve since upgraded to an iPhone 14 Pro. It’s on iOS 17.4.1. My pc is now running Windows 11 with latest iTunes. There was a glitch with synching not working with at least iOS 17.3 but it was fixed with 17.4. I can still synch my outlook 365 calendar and contacts.
