MF733CDW Cannot Scan to Email with SMTP Auth - Error 806

We just installed a new Color imageClass MF733CDW and configured it to scan to email, using the following settings: 

 

SMTP Server: smtp.office365.com

Use SMTP Auth, username: authenticatedaccount@ourdomain.com with known good password

Checked TLS

Set Networking Port to 587

 

When trying to scan to email, the printer spits out a piece of paper that says "Error".  The TX logs through the Remote UI says Error #806, which supposedly means the recipient email address isn't valid.  But we know it is.

 

We also have an open SMTP relay.  When I use those settings over port 25 with no authentication, the scan goes through just fine.

 

Can anyone think of anything else for us to look at?  We've been an HP shop until now, so I might be missing a setting in this Canon UI somewhere?  Or ... I dunno.  I'm just stumped.

Your settings appear to be correct for outbound SMTP on O365.

I have seen issues where the password (characters may not be supported or allowed).  If you are using any special characters other than alpha-numeric with one or more CAPS, try simplfying the password and retest.  Believe the printer has to be restarted after a setting is changed and saved.

Thanks for your reply.  Our password is alphanumeric only with a capital letter and 1 number at the end.  We restart the printer after every single change.  Still no joy.

I will try that, but we have the printer installed on a print server and don't use the Canon utility program on our workstations... does that make a difference to your resolution?

Hi sh_tech.

 

I apologize. I missed where you said that you were able to scan using port 25. Please try using a Gmail or Yahoo account and verify if you run into the same error.

 

If you need immediate assistance, please contact us at 1-800-OK-CANON (652-2666), Monday - Friday 10:00 a.m. to 6:30 p.m. ET (excluding holidays).
