Operations Error connecting to exchange

I am attempting to connect to my exchange email account. When I set up I receive the error

"[Exchange Web Services] An attempt to connect to email address failed. This could be caused by temporary server unavailability or incorrect settings. Do you want to check the settings?)

The error log is below
