Is there any possibility to recover the Bitlocker keys (32 digit) for the OS & data disks if Virtual Machine is not able to boot due to issues?

Question

Scenario- There is an Azure virtual Machine and the server is not able to boot due to any issues.

We need to recover the Bitlocker ID/Key (32 digit) & Password (48 digit) to recover the OS & data disks to boot and recover the server. Please help to suggest the solution to recover Bitlocker Id/Password

We have tried to attach the managed disks created from OS & disk snapshots but since the server is down we are unable to provide the Bitlocker Password information.

I tried to reproduce the same in my environment to get the Azure VM Bitlocker keys from portal:

I have created Azure Virtual Machine (Windows Server 2019) with Bitlocker Encryption.

You can recover Azure VM Bitlocker keys without logging to Azure VM from Azure Portal, even you can the fetch details if Server is down.

Note: You can fetch Bitlocker key values only if VM joined to Azure AD/ Hybrid Azure AD.

Azure Portal > Azure Active Directory > Devices > All devices > Search Your Device

Once open the device navigate to BitLocker keys (Preview), and click on show recovery keys there you will find the device Bitlocker Recovery Keys.
