Hi!
If the ID does not match your account, it means the key has been linked to a different account. No Microsoft moderator or employee has access to your BitLocker encryption key; only the user does.
BitLocker is typically activated when an account is linked to Windows for the first time. In many cases, during the initial Windows setup, you—or the person who performed the setup—might have temporarily used a different email address before removing it. The key may have been sent to that email address.
The BitLocker Key can be in any email. Check all your personal emails. Also check if any Google (Gmail) or other domain emails have the Key linked to them. Emails from other domains can also be Microsoft accounts.
- When you log into Windows or any system application using a different domain account (such as Gmail), Microsoft creates a Microsoft Account for you using your email.
- Go to the website below > Log in with one of your emails > See if the Recovery Key is saved in the Email.

- If you can't find your Recovery Key, log out of the Account and log in to another one.
- Also log in with your Google Account or another domain account that you have used in any Windows application.
- If you get the message that the account was not found, go to the websites below and see if one of them works.

- Sign in with emails of family members who are with you. Sometimes the Recovery Key may be in one of their emails.
