Answer 1

Hello,

Have you checked the following:

• Check if the recovery key is stored in your Microsoft account: If you used your Microsoft account to enable BitLocker, the recovery key may be stored in your account. You can check for the recovery key by going to https://account.microsoft.com/devices and signing in with your Microsoft account.
• Check if the recovery key is stored in Azure AD: If you used Azure AD to enable BitLocker, the recovery key may be stored in your Azure AD directory. You can check for the recovery key by going to the Azure portal, selecting "Azure Active Directory", and then selecting "Devices". If the device is listed, you should be able to view the recovery key.

Good luck!

Answer 2

Under Azure Active Directory > Devices > Bitlocker keys, search for the Bitlocker key ID. On the computer, the key ID should be displayed under the text field where you enter the Bitlocker recovery key.

BitLocker is a data protection feature that is built into Windows operating systems. It provides encryption for the entire volume of a device, protecting data stored on the device from unauthorized access. When BitLocker is enabled on a device, it requires a BitLocker recovery key to unlock the device and access the data on it if certain scenarios occur, such as the device being lost or stolen, the user forgetting their password, or the device being reset to its factory settings.

If a device that has BitLocker enabled is deleted from Azure Active Directory (Azure AD), the BitLocker recovery key for that device will no longer be available in Azure AD. If you need to access the data on the device, you will need to use the BitLocker recovery key that was provided to you when you enabled BitLocker on the device. This recovery key is typically a 48-digit numerical password that you should have saved in a secure location when you set up BitLocker.

If you no longer have the BitLocker recovery key and you need to access the data on the device, you may need to use a third-party tool to try to recover the key or the data on the device. It is important to note that recovery of the data on the device may not always be possible, depending on the specifics of the situation and the tools that are available to you.
