Azure Hybrid device registered but no MDM

[Sheridan]

We have autoenrollment enabled for our AD to auto join PCs to Azure for Intune - this works fine by and large but one specific W11 device is doing my head in

 

It shows as Hybrid Joined and Enabled but always shows the MDM as none. Leaving and rejoining several times has made no difference. The dsregcmd status shows AzureADJoined as Yes, but the TenantName in tenant details is blank

 

Short of reimaging this device (which would be a pain due to specific software packages, its a bit of a one off!) is there any way to reconnect this?

Can you do a manual enrol via Settings | Accounts | Access Work or School.

 

OR

 

Settings | Accounts | Enrol in MDM Only?

 

If nothing else, those should hopefully flag any reasons why it's failing to join Intune.

I managed to get this to check in, by leaving again, deleting a few registry keys and scheduled tasks

 

I then copied the enrollment task from another working device and ran that - about an hour later it shows as MDM managed
