Yahoo shared calendar not syncing anymore with iPhone's calendar

Hello, items I enter on iphone 12 show up yahoo calendar but items enter on yahoo calendar do not show up on iPhone. I have tried all suggestions but nothing seems to do the trick. Any other ideas?

I lost my Calendar on my iPhone yesterday. I have tried all the fixes with no results. The only twist that is different is I can enter an event on my iPhone calendar and sometimes it will show up on my Yahoo calendar on my PC. Using iPhone 13 with the latest software. Does anyone know if Yahoo is experiencing issues?

I understand that you're experiencing an issue with your iOS Calendar app not syncing with a shared calendar from your Yahoo account. While I cannot directly troubleshoot or fix the issue for you, I can suggest a few steps you can try to resolve the problem:

1. Check Calendar Settings: Ensure that the shared calendar is still selected to be displayed in the Calendar app. Open the Calendar app, tap on "Calendars" at the bottom center of the screen, and make sure the checkbox next to the shared calendar is enabled.
2. Refresh Calendars: Try pulling down on the Calendar app's main screen to force a refresh of your calendars. This action may trigger a sync with your Yahoo account and fetch the latest events.
3. Re-add the Shared Calendar: Remove the shared calendar from the iOS Calendar app and then re-add it. To do this, go to the Calendar app, tap on "Calendars" at the bottom center of the screen, tap on the "i" icon next to the shared calendar, and choose "Delete from My iPhone." Afterward, add the shared calendar again by tapping on "Add Account" in the Calendar app's settings and selecting your Yahoo account.
4. Check Yahoo Account Settings: Log in to your Yahoo account using a web browser and ensure that the shared calendar is still properly shared with your account. Verify the sharing settings and permissions to make sure they haven't changed.
5. Update iOS: Ensure that your iOS device is running the latest version of the operating system. Sometimes, updating to the latest iOS version can resolve compatibility issues and bugs.

If none of these steps resolve the issue, you may need to reach out to Apple Support or Yahoo Support for further assistance. They will have access to more specific troubleshooting steps and can provide guidance based on your device and account setup.

Remember to back up your calendars or events before attempting any troubleshooting steps to avoid any potential data loss.

Anyone had any success resolving this issue? My yahoo calendar will not sync with my Calendar on my iMac. It was fine until 4 days (or so) ago. I've been on phone with Apple support forever and they cannot figure it out. We've tried everything (deinstalling calendars, safe Mode, toggling every calendar button, etc.). Software on both iPhone and iMac both up-to-date....

Getting error 503.

Exactly the same issue here. Also happened approximately 4 days ago. Tried everything with and without Apple Support’s help. Can’t see any events from my Yahoo calendar anymore- neither on my iPhone nor on Mac. Mac shows error 503. Would deeply appreciate help. I am dependent on the Yahoo calendar and need to see it on the iPhone

I lost my Calendar on my iPhone yesterday. I have tried all the fixes with no results. The only twist that is different is I can enter an event on my iPhone calendar and sometimes it will show up on my Yahoo calendar on my PC. Using iPhone 13 with the latest software. Does anyone know if Yahoo is experiencing issues? Just a thought--I have not updated to Yahoo Plus. Have any of you updated to Yahoo Plus and having these issues?

I posted the issue on Yahoo "support". I encourage you to all add to my request and

Tag it as critical.

I also can add an event on my calendar on my Iphone 8+ and it is reflected on the Yahoo server. Events go up but nothing goes down to the phone.

Same issue: Yahoo calendar is not syncing on either iPhone 12 (17.3.1) or iPad (17.3). Have deleted and added yahoo account back several times on each but calendar is still blank.

Is there a known fix for this?

I have the same exact issue. Started 2 days ago. I tried all the suggested fixes and nothing works. If I add an entry on the iPhone calendar and it shows up on Yahoo calendar but not the other way around. Also if I delete the entry from the Yahoo calendar from the browser it does NOT remove it from iPhone calendar. it appears that iPhone can partially communicate with Yahoo calendar and post the entry but Yahoo does not do the same.

I'm having the same issue. I have deleted the account and entered it in again and the calendars still will not sync.

Unfortunately, it only synced calendars on my iPhone. My Mac is still experiencing problems. It now has Error 504 (it was an error 503 when all the devices weren't syncing)

If you added Yahoo to your Mail account previously, you might not have turned on the Calendar feature. To check this, go to Settings > Mail > Yahoo and confirm the slider next to Calendars is set to On/green. If not, turn it on.

I experience the same issue. It seems that Calendar-Yahoo integration expires after a week or so. And the only way to remedy this is to remove the account and reconnect again.

Not sure if the issue is on Apple or Yahoo's end.

My regular Yahoo calendar is not downloading/syncing either. Been happening for about 2 days. I tried everything including deleting and re-adding it but that did nothing but lost all my old data on the phone.
