Error Msg - "Calendar Invitation"

I called apple for help on this issue. I did the below

Settings>Calendar>accounts

Select the account you believe is the problem ( I have several so u can select them all)

Turn off calendar (repeat w the other ones),

Turn off /start your phone

Turn your calendar/s back on

I tried it an hr ago and so far no more pop up notifications , I even tried sending an invite and replying to other and had no issues.

But it tells me it will delete all exchange calendars - like you I have several accounts - and I'm worried about doing that because it would be catastrophic to lose all that diary info! Or would it restore?

To modify the steps for the new iOS

• Settings>Accounts & Password
• Select the account you believe is the problem
• Turn off calendar (repeat w the other ones),
• Turn off /start your phone
• Turn your calendar/s back on

So what else should you be telling us about your particular situation?

What do you know that you're not telling us about the invitation? Did you accept it? Reject it? How long ago? Did some email anomaly occur along the way? Does the organizer have a legitimate email address?

These are just examples of things you may know, but we do not know.

I have not sent any invitation.

Yes, but you did receive one.

Perhaps you can find it if you look on your calendar. Click the three parallel horizontal lines with periods next to them in the upper right. You may find this tentative event on your calendar.

I turned off the calendar as Apple instructed. restarted the phone and turned the calendar back on. Just waiting for the calendar to sync with my corp server. Thats the only thing I am worried about now. It hasnt synced yet.

I am on a corp server so they were gone for about 30 minutes and then my calendar started syncing with my server. I had all my calendar stuff back within about 45 minutes and the error message doesnt pop up any longer. Seemed to work just fine. Easier fix than what the Apple tech i had on chat wanted me to do. He was ridiculous. Hope this works/worked for you

The Above worked for me too!

Settings>Calendar>accounts

Hello,

Does anyone know why this keeps happening? I've had to go through this 'work around' several times over the last few months. Is there a permanent fix planned? Or something else? Do I need to look for the culprit in my email and contact that person who is doing something wrong?

Thanks much!

okay, I did this and it seems to have worked. It says it will delete the calendar but it doesn't at all. Just go through the steps. I turned them all off (but says delete when I toggle to button off, it doesn't)

Settings-> Accounts and Passwords

For each suspicious account select and switch off the calendar

Reboot the phone

Go back and switch on calendars.

BOOM

I know this is several months old but mine has started doing this with the most recent update. Kinda driving me batty. When I go to settings>calendar there’s no accounts setting to turn off? I’ve shut everything down, restarted and immediately it pops back up. I’ve even uninstalled the app but it mysteriously comes back. Maybe I just don’t need to be anywhere ;)

I have been following the treads and nothing seems to work. I am very frustrated with Apple...I called them too and they were useless.....They need engineers to get this figured out...I am getting error message ever few minutes...and it is very distracting while driving......

Come on Apple....it cant be that hard....

Mine was bit different. I’m using Microsoft 365

Settings>Accounts & Password>choose an account

Then turn off the Caledars, turn off the phone, turn it on again , go to same setting and turn the Caledars on.

This seems to be working too.

Yes, I also tried through the following and it worked:

Settings, accountability passwords and then I turned off and deleted each Calendar that was on. And then turned them back on and it worked. It actually fixed the view of my calendars to the way I needed to see them. So it may have had to do with my precious initiation on changing calendar views and then responding to and invite that trip these series of events. It seems as if apple has had more and more frequent issues since Steve jobs passing away. That It’s starting to feel like the quality of iphone is not worth their exorbitant price point. Hello apple get it together.

Having the same issue since the upgrade. I may have recently sent an invitation reply. I accept invitations all the time. Haven't seen any suggested fix yet in this thread. Any suggestions?
