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

Well I don't sync. my iPhone to Outlook (2013 - 32bit) all that often...

Today ... the sync. of contacts worked fine... but NOT calendar :-(


I'm not sure if it is just coincidence or not ....


Previously

I blocked iTunes from accessing the internet and had at least one successful

sync.


Now

calendar sync. Does not work … it “processes” for about 30 seconds, posts no

error messages, but does not update the iPhone calendar.


 


If anybody has any ideas … I’d love to hear them!


Here’s what I’ve tried so far…


  •  Ran ScanPST repeatedly
  • Both itunes and iphone were set
  • to 30-day sync-window  I changed them both to 90
  • tried again … no good … put them back to 30 days … no good…
  • Made sure “extra” calenders were turned off in iPhone
  • Rebooting phone, rebooting laptop
  • In iTunes sync / advanced:  “replace information on this iphone…” for Calendar only…
  • Chanced from sync “all” calendars sync only “selected” … ( I only HAVE one calendar,

but I thought it might help … no … so I switched it back to “all”.

  • Was running iOS 14.7.0   upgraded iOS to 14.7.1  (upgraded without using iTunes)

 

sigh..............

12.12.2.2 and iOS 15.0.2 -> Sync with Outlook's Contacts and Calendar(s) still works


BUT - I am seeing some oddities with Outlook categories I have selected on my Calendar events.

I have a dark-blue shade for both Business items and NCAAF games. Now, my events that were only labeled as NCAAF have both that and Business categories checked on. Not sure if iTunes is doing this or my new move to Outlook 2019 from Outlook 2010.

Thank you Ausbossy! I also agree this is so frustrating that at any moment we could lose this important function. I am ok with change, however this here is strong arming us towards icloud which is probably fine for most but NOT for me, I prefer to control my own data and most importantly keeping my "BACKUPs" local. Yes of course there are possibly a few other options, but they are NOT realistic for the average user. Anyways I'll get off my soap box now....


So after reading your response I went ahead and upgraded to 12.12.2.2 running iOS 15.2 and I too can now confirm to the community the contact synchronization feature is still working!


***NOTE TO APPLE STAFF*** Please reconsider leaving the contact and calendar synchronization in place, there are still a lot of loyal users that use this incredibly important function daily.


Merry Christmas To All !
