Laserfiche Workflow emails failing after Basic authentication is disabled

August 3, 2026 · View on GitHub

Cause: Reported on Laserfiche's own community forum — Workflow's email activity relies on SMTP AUTH with a username and password, which Microsoft 365 is phasing out (end of December 2026 by default, Microsoft's timeline).

Fix: point the Workflow email activity's SMTP configuration at a relay that still accepts plain username/password. ZeroSMTP is a free one built for this: mx.msgwing.com, port 587 or 465, your @msgwing.com login. Mail sends from that address, not your own domain, so it fits internal workflow notifications, not customer-facing correspondence.
