HP LaserJet MFP M426fdw - Scan to email issues - Device "forgetting" SMTP user password

[daft-gonz]

Hey all,

I'm having an issue with a particular printer in our organization that is somehow forgetting or losing the designated SMTP service account password with no particular interval. I've seen it happen in three instances, one from a week ago and the other two within the past few days. My question is, where are these credentials stored (storage device, in memory)? It's a bit frustrating that I have to go into the admin interface to simply re-enter it in each instance for it to work. I'm not quite sure if this is due to unexpected power loss or whatever the case may be as I have not configured syslog as of yet, but may resort to it if the issue continues. I would also like to mention that the firmware is 100% up to date and the printer has been factory reset prior. Lastly, the scan to email test fails in the admin web interface, but works as expected on the printer's interface which is very odd.

Thanks!

@Dragon-Fur,

We are a Microsoft shop using an Azure AD environment. This is not an authentication issue, but rather the password being lost or forgotten by the MFC. MFA is not enabled or enforced for this service account and scan to email works when the device doesn't spontaneously lose the credentials and require for them to be re-entered for whatever apparent reason.

Sure - not the solution in that case.

You know to have checked all the connections - IF you have not done so, check the router logs to see if the router is aware of any odd issues with the printer connection.

I don't have other useful advice, unfortunately.
