Why do I lose a Knox license seat after factory resetting my device?

Environment

All Knox Workspace or Premium versions

Summary

When I wipe a device with the EMM console command, I do not regain the Knox license seat count. I cannot use my Knox license on another device.

Cause

The device was factory reset without first being unenrolled from the EMM. By design, the license seat is not returned.

Resolution

If you already wiped a device without unenrolling it from an EMM and want to restore its Knox license seat, use the device deactivation tool. For details, see How to use the Device Deactivation Tool?.
