I'm having a frustrating issue with our Ricoh scanner that used to send emails just fine, but now it's completely broken after some network changes. Last week, we installed a new Fortigate firewall, and everything seemed fine. However, after our ISP, Spectrum, replaced the router/modem, the trouble began. Suddenly, our scan-to-email and voicemail-to-email functions stopped working, along with some glitches on IP phones. I've been troubleshooting since Monday, and while we contacted support and swapped equipment around, the scan-to-email feature refuses to cooperate. I've verified the scanner settings, including SMTP server details and ports, but I can't seem to pinpoint the issue. Any suggestions would be hugely appreciated!

One possibility is that Microsoft is phasing out basic SMTP authentication, which could be causing your issue. I recommend spinning up an SMTP2Go account to see if that resolves it. It's a quick way to test.
I think it's important to treat the scan-to-email problem as separate from the firewall issues. Check if your Ricoh scanner supports modern email authentication; that could make a big difference.
SMTP basic authentication is becoming obsolete. You might want to try using modern authentication for your scanner. If MFA is enabled, make sure the account used doesn't require it, or set up an app password specifically for the device.
Before diving deep into configs, check if your IP address changed after the firewall and router swap. Make sure you have an Office 365 connector set up for your scanner to send emails properly.

Thanks for the tip! I’ll verify the account settings and see if I can set up an app password.
