how to delete old work account

To delete an old work account that you no longer have access to, you typically need to follow specific procedures depending on whether the account is part of a managed or unmanaged organization:

1. For Unmanaged Organizations:
   If your account is part of an unmanaged Microsoft Entra organization, you can close your account without needing to contact an administrator. You would need to sign in to the account you wish to close and follow the prompts to close it. Remember that this action is irreversible, and all personal data will be removed.
2. For Managed Organizations:
   If your account is part of a managed organization, you will need to contact your administrator to delete your account. You cannot delete your own account in this case.

If you are unsure whether your organization is managed or unmanaged, you may need to check with your IT department or refer to your organization's policies regarding account management.

Additionally, if you have any data associated with the account that you wish to keep, ensure to back it up before proceeding with the deletion.
