Can't scan to email - imageCLASS MF644Cdw

[wooduck]

I'm running Windows 11.

When I try to scan to email from the printer I get error #839, which is the one saying the username or password is incorrect.

My email is a hotmail account (Microsoft). I'm certain this relates to Microsoft changing to two-factor authentication not too long ago.

I tried adding an App password from my Microsoft account, but that didn't work. Beyond that, I am at a loss.

SMTP server is: smtp.office365.com

SMTP port number is 587.

Any help is appreciated. Thanks.

Greetings,

Although I use gmail, this is what I found for hotmail/outlook.

• SMTP server name smtp-mail.outlook.com
• SMTP port 587
• SMTP encryption method STARTTLS
• Username is full hotmail/outlook email address
• Use App Password

Thanks, but unfortunately that doesn't work for me.

I think the server name you suggest is an out of date one, replaced by the one in my original message. I tried it anyway.

Also, there's no "STARTTLS" option for an encryption method. Just a "Use TLS for SMTP" check box with "Verify Certificate" and "Add CN to Verification Items" checkboxes under that (I checked all those boxes).

Anyone else with a hotmail or Microsoft365 account that is able to get scan to email working?

Office365 has made it difficult. Yes select TLS for SMTP. The other two you shouldn't need (verify cert and add CN to Verification items).

The rest your settings are correct. A note with app passwords, they are single use specific for a device. This can also make things difficult if it didn't take first time. Delete and recreate the app password. Then to verify, on the MFP side user your user name and in the password field use the one-time use one. That should do it.

Also, verify the firmware of the device is up-to-date.

Thank you. 

I tried deleting and recreating app passwords multiple times and it's still not working.

It's saying the firmware is up to date.

Any other ideas?

I just found a a document last month from Microsoft talking about requiering OAuth 2.0 for their email. Below is a link to a operator manual describing how to set this on the imageRUNNER Advance line, it hopefully will transfer to similar settings on your machine. Keep us posted please if this solves the issue.

Thank you for the suggestion. That looked promising, but I couldn't find those options anywhere in the MF644 remote UI.

[Lithoman]

I was afraid of that. I know you said the machine checked the firmware level, do you know how to find what version it is?

The TLS option is fine.  StartTLS simply means TLS and switching from a less secure authentication process to a secure one. You don't need the certificate option or the CN canonical name.  

I'll look at this again tomorrow.  It might be possible to use telnet from a command prompt for testing.

I looked at the Remote UI and under version information it says the main controller is 13.01.
