🤔 How do I use my Microsoft 365 account for outgoing system notifications?

On subscription/cloud-hosted instances, you can’t. Notifications will always come from “Notification Master <noreply@your.zammad.domain>”.

On self-hosted instances, we still don’t recommend it. Using a Microsoft account for automated, outgoing messages is risky: users who exceed Microsoft’s email sending limits can have their accounts suspended.

Set up a generic email channel instead, then use the Email Notification setting.
