Alteryx does not currently have to email tool that is configurable to use SMTP Authentication for Microsoft Office 365 or any server requiring authentication. Our office printer can authenticate over SMTP and with TLS enabled why not my Alteryx mail tool - 'mic drop!'.
Further explained, Alteryx is a tool that needs to live within abide by the policies and security standards in the organization not vice versa. Therefore, it shouldn't be a big surprise, or a big ask for that matter, that a mail client should have the ability to authenticate prior to sending email of SMTP. I'm very surprised this tool is so arcane. Please implement quickly. Thank you
