Q1: Why can’t I “factory reset” my Windows 10 device even though it’s listed in Intune under “Azure AD Devices”, however the device is not listed in All Devices
A1: Azure AD Join devices don’t allow you to factory reset. Your device needs to be enrolled with Intune MDM before the device can be “factor reset”. To enable Intune MDM run though the following
1. Enable Intune MDM integration with Azure AD: https://docs.microsoft.com/en-us/intune/windows-enroll
2. License user for EMS (AD Premium and Intune required): https://docs.microsoft.com/en-us/intune/licenses-assign
3. Device Enrolment: https://docs.microsoft.com/en-us/intune-user-help/enroll-your-w10-phone-or-w10-pc-windows
4. To force intune MDM enrolment you can install the company portal app from the Microsoft Store: https://www.microsoft.com/en-gb/store/p/company-portal/9wzdncrfj3pz
NB: if joining windows AD DS and Azure AD see Q3:

Q4: Is it possible to add the BitLocker Protector key to AzureAD? even if you enabled BitLocker before the device was Azure AD Join?
A4: Yes, the following PowerShell will need to be executed:
Add-BitLockerKeyProtector -MountPoint “C:” -RecoveryPasswordProtector
$BLV = Get-BitLockerVolume -MountPoint “C:”
BackupToAAD-BitLockerKeyProtector -MountPoint “C:” -KeyProtectorId $BLV.KeyProtector[1].KeyProtectorId
