Scan-to-email + Microsoft 365
Keep scan-to-email working when the scanner can’t use OAuth.
Start with Microsoft’s supported routes. If none works for your scanner and network, SMTPReady lets the scanner keep using SMTP locally while Windows handles Microsoft 365 authorization.
Start with Microsoft
Can the scanner use a Microsoft-supported route directly?
Microsoft documents scanners and multifunction devices explicitly. Use a native method when the device and network meet its requirements.
Does the scanner support OAuth for SMTP submission?
If it supports OAuth and the required TLS version, use Microsoft directly.
Yes → use Microsoft directly.Can your network meet Microsoft SMTP relay requirements?
If the connector, certificate or static public IP, and port requirements work for your network, use Microsoft SMTP relay directly.
Yes → use Microsoft directly.Do you only need an internal-recipient route?
Direct Send or High Volume Email may be enough. Check Microsoft’s current limits and security guidance.
Yes → check the Microsoft options.If none of those works
Let Windows handle the Microsoft side.
Keep the scanner on SMTP. Point it to SMTPReady on the private network; SMTPReady queues the message locally and sends it through your Microsoft 365 tenant.
