There’s been a lot of noise lately about Microsoft’s deprecation of Basic Authentication and how it will impact SMTP servers — especially regarding scan-to-email functionality on office copiers and MFPs. Some providers are sounding the alarm, claiming that scan-to-email will “break” come September. But let’s clear the air.
What’s Actually Happening?
Microsoft is phasing out Basic Authentication in favor of OAuth 2.0, a more secure method of authentication. This change affects how devices like copiers and scanners connect to Microsoft 365 to send emails — particularly via SMTP servers. This change only affects your copier if it is using Microsoft to send emails. It does not affect the ability to receive emails via Outlook sent from the copier.
Originally, this change was scheduled for September 1, 2025, but Microsoft has since pushed the deadline to March 1, 2026 (and even further for some protocols).
What We’ve Done About It
At A&B Business Solutions, we’ve already adapted. We’ve updated our scan-to-email setup process to use methods that are fully compatible with modern and changing authentications. We have processes in place to avoid this issue and keep companies up and running. Manufacturers have updated or are in the process of updating their devices’ firmware to support full OAuth 2.0. If you are using an email server that is making the switch to OAuth 2.0 (including but not limited to Microsoft), we at A&B are dedicated to helping you through this process. We also have alternative options we can arrange so your scan-to-email functionality is not affected.
But What About the Rumors?
Some providers have been telling customers that scan-to-email will simply stop working. That’s not just misleading, it’s incorrect on two fronts:
- Scan-to-email isn’t going away — it just needs to be configured properly using modern authentication methods.
- The deadline has moved — Microsoft has extended the timeline, giving businesses more time to adapt.
What You Should Do
If you’re an A&B customer, you’re in good hands. But if you’re unsure whether your scan-to-email setup is future-proof, or if you’ve been told it’s “unsolvable,” let’s talk.
We’ll help you:
- Audit your current setup
- Transition to OAuth 2.0-compatible methods
- Avoid disruptions when Microsoft’s changes take effect
Scan-to-email isn’t going anywhere — but Basic Auth is. With the right configuration, your devices will continue to send emails securely and reliably. Don’t let outdated advice disrupt your workflows.
