Error Msg - "Calendar Invitation"

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

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.

That is correct.

Settings-> Accounts and Passwords

For each suspicious account select and switch off the calendar

Reboot the phone

Go back and switch on calendars.

Just did it and it seems to wo

Your email is all server based so it will just re-sync and reload everything when youbadd the account back on.

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

Worked like a charm. Upon restart give your calendar a few minutes to repopulate.

Switch to MS outlook app and use that calendar instead. Better in most ways.

I have an exhange acct and I got the same - will delete

- backed up my device with icloud just in case

anyways all my calendar events came back

- hope this helps

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.

Hi,

i have Iphone 6S+ under Settings, Calendar there is no accounts.i can see Allow Calendar to Access then time zone etc...

Regards

If they are synced to the servers, they should come back when you re-enable them. It worked for me.

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....

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?
