Introduction
BitLocker encryption is crucial for data protection, but when keys fail to upload to Entra ID via Microsoft Intune, it can cause frustration. This article provides a solution for IT admins who enforce BitLocker and encounter this issue.
Why Do BitLocker Keys Fail to Upload?
Incorrect policy settings or improper order of operations can lead to BitLocker keys failing to escrow to Entra ID.
Required Policy Settings for Automatic Key Escrow
- Enable Save BitLocker recovery information to Entra ID
- Set Client-driven recovery password rotation to enabled
Order of Operations: Encryption then Registration vs Registration then Encryption
Ensure that devices are encrypted before registration, or register the device first and then encrypt it.
Manual Key Escrow via PowerShell BackupToAAD-BitLockerKeyProtector
$keyProtectorId = (Get-BitLockerVolume -MountPoint C:).KeyProtector[0].ProtectorTypeId
BackupToAAD-BitLockerKeyProtector -MountPoint C: -KeyProtectorId $keyProtectorId
Verifying Key Recovery through Intune Admin Center
Check key visibility under Devices > device name > Recovery keys in the Intune admin center.
For Cloud-Only Devices: Ensure Azure AD Joining
Ensure that the device is Azure AD Joined, not just Registered.
