Question: Iphone X
I have a IPHONE x and I can not get calendar invites addressed to my Optimum email. I was able to in the past. The email works fine sending and receiving. it is only when somebody sends a calendar invite to my optimum email address. I just never receive it. My wife has a optimum account and I can send calendar invites from my Iphone to her Iphone X and she receives no issue.
iPhone X, iOS 11.2.6
