Wipe with no logged user

Hello Community,

I'm writing this post to submit at your opinion an issue related to device wiping through Intune.

Scenario

There are two Windows 10 21H2 devices, Azure AD joined (no Hybrid), managed by Intune (no Autopilot/hash imported) and assigned to end users.

On both I launched a wipe with "Wipe device, and continue to wipe even if device loses power. If you select this option, please be aware that it might prevent some devices running Windows 10 and later from starting up again.". Their status appears as protectedWipe pending...

The wipe didn't occur (waiting more that 30 minutes).  They are both connected to wired network and can communicate to Internet. There is NO LOGGED user there.

After I logged on Windows into one of them, then the wipe started.

Does the wipe need a logged user to work ? I suppose, not (there is no reference about this on Microsoft articles - if yes, I didn't find it). Of course, there is a reason about this behavior.

Please, any useful information could be appreciated. Meanwhile, I'll start investigating the Intune logs on the device.

Thank you,

Luca
