You can start by calling your regional Microsoft support hotline here: Customer service phone numbers - Microsoft Support and choose Work account.

6. During the phone call, you will need to provide the information associated with your subscription, such as your company name, billing details, phone number, and an alternate email address, etc. This information allows the Data Protection team to verify your identity and securely assist you in regaining access to your administrator account.
