Scan to email not working on M477fnw

HP Recommended
LaserJet Pro MFP M477fnw
Microsoft Windows 10 (64-bit)

Scan to email stopped working recently. Error is "Username or password is incorrect. Ensure both user account and password are valid." Happening on two separate email accounts, Outlook and Gmail. Just stopped working, so not likely to be password issue. More likely some SMTP/IMAP issue?

For Outlook, using port 587 as SMTP server, and using authentication.

Hard reset printer, no change.

Any help would be appreciated.

This is more likely due to security changes of the mail.


For Gmail, check its security settings as following:


First, open the following link and login to the same account as you set for the printer.

Note: if you are connected, sign out from your account, select your account and manually enter the password to ensure you indeed use the correct password, then click on Security from the left pane:

Within the Signing in to Google section, check the "2-Step Verification" velue.


If it is set as "On", create and use an App-Specific Password with the printer:


If it is set as "Off", Within the Less secure app access section ensure that the feature is on.


If it is Off, click on Turn on access (not recommended) and toggle on the feature. Otherwise the verification will fail.
Once you are done run a test for the outgoing user profile and check if the problem been resolved.


For Outlook, try creating an App Specific password and check if that may work:


Please let me know if that fails, I believe they should have an Less Secure app setting too.
