When setting up the account choose Yahoo & enter your Sky email & password, you should then be taken to a Yahoo page asking you to sign in to authenticate adding the account. 

Once complete the account will continue with setup.

If the account has already been set up & it's asking for a password then either delete the account & set it up again as above or create an app specific password. Microsoft upgraded their email security recently so accounts now require authorising or an app specific password in order to be used with MS email clients.
