Former employee’s Microsoft account inaccessible – urgent BitLocker key needed

Hello,

We urgently need access to a BitLocker recovery key for a company device, but we cannot access the Microsoft account associated with it.

Details:

  • Microsoft account: <removed PII>@miyawaki-kogyo.co.jp
  • Recovery key ID: 06FA5A35-<removed PII>
  • Device name: DESKTOP-<removed PII>
  • OS: Windows (version unknown)
  • Error code: AADSTS50043

The account belongs to a former employee, and we do not have access to their phone number. We know the password, but we cannot receive the verification code by email, so we are unable to sign in.

We have already checked spam folders and mail filters, but no code is being received. There are no other verification methods available.

We have started the security info update process, but we urgently need access to the recovery key and cannot wait for the full update period.

Is there any way to verify ownership or retrieve the BitLocker recovery key without access to the original contact methods?

We are a small business and do not have an IT administrator. Any help would be greatly appreciated.

Thank you.

    To retrieve the BitLocker recovery key for a device associated with a former employee's Microsoft account, you typically need to verify ownership of the account. Since you have the recovery key ID and device name, here are some steps you can take:

    1. Contact Microsoft Support: Since you cannot access the Microsoft account due to the lack of verification methods, reaching out to Microsoft Support directly may be your best option. They can guide you through the process of verifying ownership and potentially assist in retrieving the recovery key.
    2. Helpdesk Recovery: If your organization uses Microsoft Entra ID or Active Directory, you may be able to retrieve the recovery key through your IT helpdesk. Even if you do not have a dedicated IT administrator, check if there is a contact person or a support service that can help you with this.
    3. Self-recovery Options: If the BitLocker recovery keys are stored in Microsoft Entra ID, you can access them by signing into the Microsoft account associated with the device. However, since you mentioned that you cannot access the account, this may not be applicable.
    4. Documentation: Gather all relevant information about the device and the account, including the recovery key ID and any other identifiers. This information will be useful when contacting support.

    Unfortunately, without access to the original contact methods or the ability to verify ownership through the standard recovery processes, retrieving the BitLocker recovery key may be challenging. It's crucial to act quickly and reach out to Microsoft Support for assistance.

    Dear 小林 裕詞,

    The BitLocker recovery key for a device joined to Azure Active Directory is stored within your organization's tenant, not the individual user's account. Since you have the recovery key ID and device name, access the Azure portal with a global administrator account for miyawaki-kogyo.co.jp. Navigate to Azure Active Directory > Devices > All devices, locate DESKTOP-M45P7CB, and select Recovery keys to retrieve the key directly. If no administrator account exists, you must contact Microsoft Support with business verification documents to prove domain ownership and initiate account recovery.

    I hope you are clear with the information. Should you have any more questions, feel free to leave a message. It's really appreciated of you to accept the answer to help build the community by sharing your experience with the issue. Thanks!
