If your old Microsoft 365 account was hacked and you lost access to it, you will need to follow Microsoft's identity verification processes to regain access or recover your products. Here are some steps you can take:
- Confirm Account Ownership: Go to the admin portal and try signing in with any previously used email account. If prompted, follow the steps to request admin access.
- Submit a Support Request: If you cannot regain access through the portal, submit a support request by visiting the Microsoft 365 support page. Select "I can't sign in or access my tenant" and be prepared to verify your identity and ownership of the organization through official business documentation or domain ownership.
- Contact Your IT Partner: If your Microsoft 365 tenant was created or is managed by a Microsoft partner, reach out to their support team for assistance.
Unfortunately, transferring products from the old account to a new one may not be straightforward, as it typically requires access to the original account.
