Kyocera printer "Send Error 1102" / 0x1102 sending scan-to-email via Office 365

Cause: Error 1102 (0x1102) on Kyocera MFPs is the device's code for an SMTP authentication failure. Against Microsoft 365 / Exchange Online, this is almost always Basic authentication for SMTP AUTH being rejected — Microsoft is switching this off by default at the end of December 2026 (official timeline). Kyocera offers an Exchange Online Connector (EOC) utility for supported devices as the official OAuth path.

If EOC isn't available for your model, or you want a simpler fix: point Command Center RX's SMTP settings (Advanced → E-mail → SMTP) at a relay that still accepts plain username/password. ZeroSMTP is a free one: mx.msgwing.com, port 587 or 465, @msgwing.com credentials. Sends from that shared address, so it's for scans that just need to arrive, not customer-facing mail.
