How do I disable Outlook calendar annoying warnings?


I am using Outlook 2019 on Windows 10

Every time I move an appointment that's part of a series, I get a warning notification,

"you changed the date of this occurrence of "xxx event". To change all the dates, open the series. Do you want to change just this one?"

It pops up every time I change an occurrence and there is no way I can find in the option to this warning off. It is so annoying.

Does anyone know how to turn it off?
