Canon Maxify Printer & Authentication
I recently added Microsoft Authenticator for all our domain email accounts. I have an account that I use for devices and applications to send emails to our domain internally. In each app, I re-tested the account, went into Microsoft Authenticator, approved the request and sent a test email: the apps work!
My problem is my Canon Maxify printer. I entered the following information:
sender address: user@ domain.com
Outgoing mail server SMTP: smtp.office365.com
Port Number: 587]
Checked on Secure Connection (SSL)
Checked on Don't verify certificate
For authentication: SMTP authentication
But it doesn't work. Do I need to enable a setting in Microsoft Entra and Exchange to get this to work? It is important that the printer send me status messages so I know when there is an issue. I also want to add that the email settings were working until I added the Microsoft Authenticator. Thank you!

Your Canon used authenticated SMTP until MFA was introduced, and its SMTP test now fails although the mailbox credentials worked before. An Authenticator approval is an interactive sign-in; most multifunction printers only implement username-and-password SMTP and cannot complete it. First, turn certificate verification back on and confirm the device supports TLS 1.2 or later. For internal status messages, the cleanest replacement is an HVE account: assign its billing policy, use smtp.hve.mx.microsoft on port 587 with TLS, and authenticate with HVE credentials or OAuth if supported. If HVE is unsuitable, direct send can use your tenant MX endpoint on port 25 without authentication for internal recipients, provided your network allows port 25. SMTP relay is another option when you have a static public IP or suitable certificate. Avoid weakening tenant MFA or security defaults for this printer.
