Keep scan-to-email working with modern Microsoft authorization.

Where smtpify365 fits

For multifunction printers and scanners that support authenticated SMTP and STARTTLS but cannot complete an OAuth browser flow.

• Use a separate revocable connection for each physical device.
• Set port 587 and STARTTLS rather than implicit TLS on port 465.
• Use the connected mailbox as the envelope and visible From address.
• Test a small PDF before testing address books or large scans.

A simple migration path

Authorize the Microsoft 365 mailbox, store the generated one-time credentials in the client, then send a controlled test before enabling production notifications.

Know the boundary

smtpify365 preserves the SMTP client interface but does not bypass Microsoft sending limits, filtering, mailbox policy, or final-delivery processing.
