Fix: Error “Your Response to the invitation cannot be sent” on iPhone?

The users can then respond to the invite by accepting or rejecting it. One of the commonly faced problems by the users while responding to a Calendar invite is that they are unable to respond to that invite and the iPhone or iPad displays the message to the user “Your Response to the invitation cannot be sent”.
