HP LaserJet 500 SMTP delivery failure

Hi snoopaloop,

If I understand you correctly, you are setting up these mail setting in Log > Automation section of your SonicWALL. This section is only for logging purposes for your SonicWALL exclusively. These setting do not setup relays in any other way for other devices in your network. Does that make sense?

If you want to send notification from your printer you need to configure them in the printer settings for mail servers not in the SonicWALL.

To properly setup an SMTP Client Submission for Office 365 the preferred method is to use 587 opposed to 25, enable TLS and the mail server should be smtp.office365.com not outlook.office365.com. Change them and try again!

Also, SMTP transmission can be reduced by disabling IPv6 and DHCPv6 under the Networking tab in your Printer Settings, unless you use IPv6 in your internal network.

Let me know if you have any other questions!

Yes, I understand what the Sonicwall is doing and I know that it is not performing any SMTP relay.  I brought it into the conversation because the SMTP settings that successfully work there, do not work on the HP.  Microsoft support team gave me those configuration settings when I set that up.  Now I have an HP MFP that needs to be some SMTP delivery of messages as well.  Anyway, I tried your suggested settings and I received the same error message...

Are you filtering outbound traffic on the SonicWALL? From the screenshot you posted it looks like there is an internal error with the MFP - everything is checked green but the red error at the top says otherwise. That doesn't make sense...it looks like you are connecting to the Exchange server. Make sure the firmware of the MFP is most current.

Office 365 SMTP Client Submission (the preferred method) may not be compatible with that printer. Use the Direct Send method:

You have to modify your SPF record by adding an entry to it below to avoid having messages flagged as spam. If you are sending from a static IP address, add it to your SPF record in your domain registrar’s DNS settings as follows:

Also, something to note with this method is that it can only send to users within your organization. If you want to send to users outside your organization you should implement the Office 365 SMTP Relay as noted in the link below.

Let me know how this goes!

Have you tried tweaking things in the connector settings in O365?

I posted again but no response from you. The more you interact the faster we can resolve this for you!

Not all devices are created equally. Some devices may not support any of these methods proposed by MSFT. You may need to setup IMAP or POP configuration and even then they may not work.

I escalated to Microsoft O365 upper tier level support.  They should call me back either today or tomorrow.

Thanks for the update. Waiting for your response after they get back to you. Please let us know what they found!
