iPhone calendar stopped syncing

Yes, it has been enabled for ages.

As a reminder, this syncing issue is also happening to people with non-Yahoo accounts. I specifically am aware of people with Outlook and Gmail having the exact same problem.

I appreciate you trying to help, but I’m not sure why you keep trying to deflect this back to Yahoo (and presumably Outlook and Gmail).

It is not “happening with the Yahoo Mail App and not with the Apple Mail app”. I can access mail through either of those apps just fine.

The issue is ONLY with Apple’s Calendar App and since Apple’s Calendar App keeps erroring out that my password and email don’t match my calendar will not sync.

Meanwhile, APPLE’s Mail App is perfectly happy with my password and email and as you inquired earlier, I do utilize two step authentication.

Because in one of my attempts to solve this problem I changed my Yahoo password- I had to re-sign into my APPLE Mail app utilizing the new password and two step authentication. Which worked perfectly fine for Mail.

However, the APPLE CALENDAR app continues to error out.

Others have suggested deleting and reinstalling either/both APPLEs Calendar app or my Mail account - but since my calendar is not backed up anywhere (since it won’t sync…), if I do that I will lose all calendar entries that were made since this issue started.

And for the record, I previously did go to Yahoo too. Guess what? Since the problem ONLY happens in APPLE’s Calendar App they directed me to Apple.
