If the BitLocker recovery key cannot be found in any of the usual locations (user's email, Microsoft account, Azure AD, Intune, on-premises Active Directory, local machine, or external media), unfortunately, there are no official methods to recover the BitLocker recovery key for the locked drive. The recovery key is essential for accessing the data on a BitLocker-encrypted drive.
If the recovery key cannot be recovered, there is no supported method to disable or remove BitLocker from the D: drive without losing data. BitLocker is designed to protect the data on the drive, and without the recovery key or password, the data on the drive cannot be accessed or recovered. This is a fundamental security feature of BitLocker to ensure that unauthorized users cannot access encrypted data.
Therefore, it is crucial to store recovery keys in a secure and accessible manner to avoid such situations in the future.
