iphone calendar stopped syncing with Outlook on PC

I use iTunes on my Windows 10 computer to sync my iPhone SE (2020), and it has previously worked with Outlook just fine. It syncs my calendar and contacts from my Apple calendar and contacts apps. (I have MS Outlook 2013.) About 2 months ago, it stopped syncing the calendar from the phone to the PC. None of the settings have been changed. There was an upgrade to iOS 15.5 on the phone, but that appears to have occurred after the calendar sync started failing. Contacts still sync with Outlook. Syncing via iCloud is not an option for me.

Any thoughts or suggestions? Thanks in advance...

Microsoft was not able to figure out the problem. I do recall that we received notice several months ago that *future* versions of iTunes would no longer sync calendars and contacts. I have version 12.12.4.1 by the way. I didn't think there had been an iTunes software update, but I see that it was released in May, so I guess my computer did an automatic update. Does that sound like the cause of my issue? If so, is there a way to revert to the earlier version of iTunes?

Howdy AnnLD,

Thanks for giving that a try and updating us with this information.

Check out the suggestions below to see if those may help to resolve this for you. If not, check out the additional information here: If your iCloud Contacts, Calendars, or Reminders won’t sync - Apple Support

Things to check first

1. Check the system status of iCloud Contacts, Calendars, or Reminders to check for services outages or connection issues.

2. If a reminder isn't showing up on some of your devices, make sure that your iPhone and iPad have the latest version of iOS or iPadOS, or that your Mac has the latest version of macOS.

3. Make sure that you're signed in to iCloud with the same Apple ID on all of your devices. Then, check that you turned on Contacts, Calendars, and Reminders in your iCloud settings.

4. Check the date and time settings on your device to make sure they're correct for your current location.

If that isn't helpful with allowing the sync to occur, check out the following resource for steps to take in regards to issues with Outlook: If you can’t add iCloud Calendars, Mail, or Contacts to Outlook - Apple Support

We hope that's able to help!

Cheers.

AnnLD,

You mentioned this sync was happening through iTunes, versus adding your Outlook account to your devices and having the sync happen via Outlook's servers.

How often are you connecting your iPhone to your computer for that sync to complete? Are you also noticing an issue with data syncing from your computer to your iPhone?

Thanks.

Just an FYI - I had noted in my previous reply that I was aware of the pending change in iTunes for Windows, that it would no longer sync contacts and calendar. So I did try reverting to the previous 2 versions of iTunes (12.12.3.5 and then 12.12.2.2), and neither made a difference in syncing my calendar.

Is anyone familiar with the plan to discontinue syncing with Outlook? It was supposed to occur "in a future version of iTunes," so I assumed going back to a previous version would fix this problem, but alas...
