E-Mail Sending Has Stopped Working On Hardware Devices

In most cases like this, we run a Postfix server on Fedora that accepts unauthenticated port 25 from the devices and then sends out authenticated through O365 or whatever. Often that's the only way.
Feels like a smtp relay for sure is the best way to handle networks where you have devices sending email.
Just imagine changing ISP or whatever and then have to go through all email capable devices to make sure they now have the proper outgoing email settings.

OK, that's what the connector is supposed to fix. authentication is IP based instead of username/password based.
did you confirm that your PC's external IP is the same as the IP you provided in the connector? (google - what's my IP?)
Yessir...shows correct IP Address.

I believe this is going to be in my near future...just weird for it to BAM! and stop...makes me wonder if I have a network issue...I had a feedback loop a few months ago that drove me crazy until I could finally locate it...

This is wrong. There’s no issue because I connector validates by your IP. If you get a new ISP you update the IP. That’s it done. A relay is useful so that you only need to send out from one local device, and thus you can blacklist SMTP out for everything except that One device. But that is not directly related to sending email out via a connector.

I use the relay simply because port 25 is not allowed to be sent out of my network except from the relays IP address. You do not have that restriction, so you do not need a relay for that reason. You have obviously set something up incorrectly in your connector. I’m driving home tonight but I can screenshot mine and/or other clients tomorrow

What's the security on your connector?
Should include anonymous

That may be part of the problem...I do not see these options for my connector...is it on a different screen? I also didn't see these options when setting up the connector.

Thank you...that was helpful...it looks like I did set it up correctly...that said, I do not have options like in this photo below...

That looks like an on prem screenshot. Office 365 does not have a screen like that.
Edit: Yup. Here is Exchange 2013 ECP.

@JaredBusch Not sure if more impressed that you made all those screenshots, or horrified at how Microsoft buried that setting.

It's not buried. it is right there. Just lots of clicking.
You can do it all with PowerShell also, but I don't know the commands. I do not set up enough connectors to have ever bothered to learn that.
This is a once and done, for the most part, at a client.

@garak0410 That means your copier should now work.
Plain SMTP, no authentication, or anything.
The only requirement is that it has to use a from address of [email protected]

Sadly, same on both Toshiba Copiers, HP Printers and Dell VTRX:
Failed to connect to SMTP server
SMTP protocol error

Do you ever have those IT moments where a fix to something makes you feel foolish but those in your field, especially in a SOLO IT SHOP can totally relate...
Well, this is working now...and almost too embarrassed to say why...but I will...
IP Address was wrong...mind you, we used the same one for years...YEARS...and I've spoken with Microsoft Office 365 support 3 times and they know which IP address I was using...why couldn't they have simply said "Oh, this is the problem..."
It was going to a direct IP address and stopped working...
I tried the DNS name and no go.
Finally, though @JaredBusch's awesome help, it exposed the real IP address to use...and it is fully working now...I do wonder why it just stopped working...but grateful for the help. Hope to see a few of you at SpiceWorld...

Oh, you were using an old O365 IP address? Yeah - that's what sucks about using IPs instead of DNS entries. If you change the IP, you have to change everything that points to it... but if you use a DNS entry instead... they change where it points and all remains good.
