Calendar Invitation: Response to the invitation cannot be sent

Do you mean we need to click on Delete from My iPhone when that appears after turning off the calendar? I tried just turning the calendar on and off again in settings/accounts and passwords but the pop up came back up. Thank you,

Hi,

I have the same problem but cannot follow the steps.

I see that you recommended going to Settings>Calendar>Accounts...however when I go to Settings>Calendars it does not give me an option of "Accounts" - was this changed in the last software update? or am I missing something?

Do you have another way to get rid of this error message?

I've tried hard restart and unsyncing calendars, etc but nothing is working and the message keeps popping up.

Thank you

You went to settings,acct & passwords your work account and made sure calendar is checked on? It worked for me. Also make sure you’re on the most current update. I’ve had to shut my phone off just to receive text messages. It’s geting worse And worse every day.

For the IOS 11 replies...

Some of you are are going to settings > calendar.

The advice is to go to settings > accounts and passwords. Under the section for App and Website Passwords, click on the account which is having the Calendar invite issue.

Within that account, you will have the toggle button to turn off the calendar.

Once I did these steps, I power cycled my phone and followed the above steps to re-enable the calendar sync. I am no longer receiving the pop up.

There are no addresses to turn off in the Calendar app on my SE. These calendar error messages have been repeating for several weeks. I turned everything else off in the calendar app, and they persist.

I tried one of my calendars -- and deleted it. It did not sync back up. Fortunately it was a test calendar and I didn't lose anything. I am not going to risk losing my work calendar. I am also tired of the message popping up...

It finally went away... Someone sent me an invitation to attend a meeting and when I responded "Decline," I stopped getting the recurring messages... No problem now. But what happened to cause it?...

I’m having th same issue with recurring pop up invitations. Extra challenge to all of the above posts: this invitation has several monthly recurring calls (two separate invitations set to recur in perpetuity) that I no longer have access to (don’t work there anymore). The account is off of my phone, so it has already been unsynced and account deleted. I’m still getting the pop up (about 7 every time I open my phone just from sleep, and several during use depending on time used will get dozens). Please, please help.

I’ve done everything mentioned above in this thread— accounts deleted, removed the calendar, replied to the invitations decline (they’re bi-monthly recurring calls in perpetuity), updated phone and restarted half a dozen times. Please help, I’m desperate, this issue has been Happening since I left the company in early December... pulling my hair out.

it only clears the problem when I hit delete For all the calendars (Gmail and a work exchange) After i powered down and turned it back on, my calendar was clear, then I went back into Accounts and Passwords, toggled the calendars back on and the calendars resynced. It is a bit nerve racking, but it did work. Now Apple needs to fix the root cause of this problem!

I’m having the same issue. I’m on ios 11 and it seems there isn’t Account choice under calendar any more. Do you have any other alternative solution?

Go to settings accounts and passwords calendar turn off and back on it’ll say it’ll delete but it’ll sync up afterwards

Same here. Help appreciated.

thank you so much Jsantos421! This worked on iOS11!
