My client is unable to access the Outlook account. Could you please check this issue and let us know the cause?

Additionally, could you guide us on how we can access the admin portal?

Hi,

My client is using a business account and is facing an EStack Error: 500. I’ve attached the screenshot for reference.WhatsApp Image 2026-01-22 at 12.53.31.jpeg

The issue is that when trying to log in to the admin panel, it asks for a verification code sent to an email address, phone number, and password. However, the client does not have access to any of these three options.

Recently he didn't receive any emails. could you please help me?

Hi @vaithee p

I would like to reconfirm your client's account type to make sure we provide the correct troubleshooting steps. Please let me know which of the following applies to your account:

Personal account (e.g., @hotmail.com, @outlook.com)

Educational account (e.g., @schoolname.edu)

Business account (e.g., @yourcompany.com or @onmicrosoft.com)

If your client are using a "business account", the only way to regain access is to contact your "IT administrator or Global admin" and request a phone number update in the "Microsoft Entra admin center".

In the Entra admin center, an administrator can set user accounts to require a re-enrollment of multi-factor authentication (MFA). Ask your administrator to follow the steps shown in the following article:

Manage user authentication methods for Microsoft Entra multi-factor authentication

Sign in to Microsoft Entra - Microsoft Entra admin center

User -> all users. Select the user you want to act on, and then select "Authentication methods". then select "Require multi-factor authentication re-registration".

Require re-enrollment MFA: This disables all previous authentication methods. You'll then be prompted to set up a new MFA authentication method the next time you try to sign in, so you can add a new authenticator app.

I highly appreciate your valuable time and your cooperation during this process

Please let me know if I can do anything more to support you!
