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!
