In case anyone is struggling to scan from an Imagerunner Advance to a Hotmail account, I found this resolved my issue:-
Login to the Hotmail account at Microsoft account | Sign In or Create Your Account Today click on security, more security options then scroll to app passwords and generate an app password. Use this password in place of the email address password on the imagerunner smtp authentication settings. Scanning should now work.

smtp server=smtp-mail.outlook.com
Port 587
SSL on.
