Calendar Invitation: Response to the invitation cannot be sent

Jsantos,

Thanks for the advise. I’m having the same prob. The only thing is not clear to me is: do I just turn the calendar on/off, or do actually click on delete account, then turn phone off?

Thanks!

This works for me as well !!! Thanks a lot.

The real answer is always in the comments! You da man or woman as case may be.

I have the same problem. Will I loose my calendar appointments?

I clicked on the Delete From My iPhone button and it worked just fine. Did not lose my appointments.

Account Settings have been elevated into Settings>Accounts & Passwords>

and Calendar is one setting inside each account linked with your iPhone.

Yes! This worked! Many thanks!
