Response to invitation cannot be sent

I figured it out, Go to Settings > Accounts and passwords>(here is the trick ) One of your Email Addresses that you responded to an invitation for is rejecting you response 5, 10, 15, second, minutes, hours, days, or years ago until now. Think back to what email invite that was when this start happening then turn that email (calendar) Off. You will get the warning message pop up {Delete from my Iphone} DO IT! Hold The Restart Button wait for it to turn on and go back into Settings> Accounts and Password and find the email address that had the (bug) turn > Calendar back on Problem Solved its been an hour and I haven't had any pop ups (OH YEAH BABY). It took me two weeks to figure it out.

Go to Settings > Accounts & passwords>(here is the trick ) One of your Email Addresses that you responded to an invitation for is rejecting you response, turn off calendar, delete from my iPhone will pop up, you will need to select it, you will then need to reboot your iPhone, when power is regained you can then turn your calendar back on.

AWESOME!!! This absolutely fixed the annoying pop up on my Iphone 7 Plus. I use exchange/outlook calendar at work and gmail calendar for personal items. I followed the steps and although I was concerned about the 'delete' part, did it anyway, and yes the calendar items do disappear for just a few moments, but they re-populate. Mine only took 2 minutes. Thanks BBOYOILY 🙂

I need help with relentless pop ups. This solution does not seem to work with iOS 11.0.3 as there is no such thing as Settings > Calendar > Accounts anymore so no option to turn off or remove a calendar and then turn it back on. Any suggestions?

My iPhone 7 on IOS 10.3.1 does the same. I communicate with an Exchange Server and my private e-mail server. This message started appearing on Tuesday after I worked on a site, reading my exchange e-mail calendar invites. Can it be switched off or fixed? It is very frustrating t continiuously have this message flash and then you cannot use the phone till you respond to the message.

Well done. It worked a dream. How blokes like you work out these answers is magic to me!!

Love to help youbare welcome

Yes Mr Frontman glad I can help boss

This worked, thank you!

Thank you. This worked.🙂

I started having this problem as well. I tried to even restore the phone but of course I did a backup restore, however the issue is still back. How can this annoying problem be resolved?

Does Apple folks even read these discussions and respond or is it just the users discussion group?

Almost same problem here. I can accept an invitation sent to my 4S. But I get an error: "cannot sent an invitiation response!" when I accept the invitation.

Is there someone with a solution pls?

I heve the same problem.

I would be genuinley happy if someone could tell me how to turn off this ridiculously repeating popup. One would think that after telling me about a thousand times that the response can't be sent, I really do get the message.

Hello Howard,

did you find a solution to this problem? I have the same pop up on my iphone. I have no idea how to turn it off/interupt this.

Any help would be much appreciated.

Thanks,

Deanna
