Hello Tomás Geovanny Santander Acosta,

Thank you for connecting with us in the Microsoft community.

According to your description under "Microsoft 365 and Office / Install, redeem, activate / For education / Android" support category,

I did not find key information in your case description.

But I will provide the following information based on our support limits. Because, since we are from the Microsoft 365 Business/Education support team and provide potential address information for Microsoft 365 Business Basic/Standard/Enterprise/Education subscription services related to this forum support category.

My response will be with detailed process information for different kind of user role account so please read carefully my below provided brief response.

Please note that since we forum community moderators do not have any permissions or resources to verify and run any backend processes in this public community for email account hacked related situation. Because this case is sensitive and related to the security of the email account. This entire case can be verified by a dedicated support team from your backend resources. But at least we can try to provide the necessary direction for your concern.

I need to break this scenario in two different kind of email account role:

1. Student or End user role account (i.e. no admin privilege).

2. Microsoft 365 Global admin role account.

===============================================================================================

1. End user account Role (i.e. no admin privilege).

In the order of the given scenario, If your email account is related to Microsoft 365 Business Basic / Standard / Enterprise / Microsoft 365 Education subscription service which is provided by the Office 365 global administrator of the related Office 365 business tenant organization and if you are an End user person, you will need to contact the Office 365 global administrator of the enterprise tenant organization for an MFA-related situation.

Because they're managing or resetting end user's email account from their side by admin center. Responding to a Compromised Email Account - Microsoft Defender for Office 365 | Microsoft Learn

If it is necessary, the Office 365 Global Administrator of the related organization can also contact Microsoft's frontline support team via an open service request from the admin center for further resolution of the situation related to end-user two-step verification.

After diagnosing the scenario, our technical support team can provide possible information and guidance on their part to the administrator.

For this standard process, here's the official Office Global Administration Reference document: Get support - Microsoft 365 admin | Microsoft Learn(online option).

2. Microsoft 365 Global admin role account.

If you are global admin person for this situation, you will have to contact to Microsoft's specific support team via usingPhone support resources, they will further help you from the backend side.

Because, the Office 365 global admin account or Office 365 Business tenant access related scenario will be handled by Data Protection team. Our Phone support team may help you to escalate this situation to appropriate team (i.e. Data protection team) via opening case request from their side.

For this sensitive case, standard process will be required from the Data protection team, and this team may take few days to perform their confidential and standard process with necessary protocol.

Here is official document about:Find Microsoft 365 for business support phone numbers by country or region - Microsoft 365 admin | Microsoft Learn

Just for an example reference: I am sharing one thread URL where one Microsoft Agent Moderator has mentioned some detailed information about phone support:I cannot Login to my Admin Account - Microsoft Community

Note: Phone support team or AI may ask for subscription, domain, phone number or alternate email address for verification process.

Currently new calling process has been implemented by Microsoft. If call hangs up, you may need to attempt call several time to get support from phone support agent to escalate your case to Data protection team.

Here are some important notes:

End users should contact the Office 365 global administrator of their respected company, school, or university organization to perform some standard process and connect with the frontline support team for further resolution.

If an organization's Office 365 Business/Business/Education subscription is from a syndicated partner or reseller, and if the global admin can't open the service request on your end, you might need to contact the reseller's support provider so that they can help the global admin open the service request on their end. after the Office 365 support team participates in the service request created.

Note that the above all the process information applies to Microsoft 365 Business Basic/Standard/Enterprise (E3/E5)/Microsoft 365 Education subscription services for different kind of role account.

===============================================================================================

If your email account has been associated with different subscription services, such as Office 365 Family/Personal/Home & Business/Home & Student/Outlook.com, you must provide information about your subscription for further instructions. Since there are several different types of Microsoft accounts and subscriptions, they have different service and support options.

I would greatly appreciate your valuable cooperation.
