Hi @Amaaz Arshad
To customize the "Forgot Password" email in Azure Active Directory B2C (Azure AD B2C), you need to use a third-party email provider or a custom REST API. This customization is part of the password reset flow and allows you to define the content and format of the email sent to users.

You can use providers like Mailjet, SendGrid, or SparkPost to create your own email templates and specify the "From" address and subject line.

Custom email verification and customization are only available through custom policies, which you need to configure in your Azure AD B2C tenant.

Create an email template that includes the verification code and any other necessary information.

Configure your Azure AD B2C custom policy to use the email provider and the template you've created. Custom email verification with Mailjet (b2c-user-flow) Custom email verification with SendGrid (b2c-user-flow) Set up a password reset flow in Azure Active Directory B2C (b2c-custom-policy)

Hello Amaaz Arshad,

I understand you're trying to customize the "Forgot Password" email in your Azure AD B2C setup.

In Azure AD B2C, the default verification email sent during password reset cannot be customized if you're using built-in user flows. The email content, subject, and layout are managed by the system and can’t be edited.

If you want full control over the email’s content, formatting, and sender details, you need to use Custom Policies (also called Identity Experience Framework). With this setup, Azure AD B2C calls your custom REST API, and your selected email provider (like SendGrid or Mailjet) sends the email using your own template.

You can refer to these Microsoft guides to set up custom email verification:

If you're new to custom policies, this guide will help you get started:

Tutorial - Create custom policies - Azure Active Directory B2C

Hope this helps to clarify things a bit. Let me know if this answers your query, and feel free to post back if you have any further questions.

Hello @SrideviM

I tried your solution with mailjet and it worked. I had one problem though, my company wants to customize email using Azure smtp server i.e. Azure Communication Services (ACS) instead of third party smtp servers such as sendgrid or mailjet, but i think that the documentation only provides custom email templates of forgot password in custom policies with sendgrid and mailjet. Can you help me on this?

Hello Amaaz Arshad,

Thanks for the update, and Great to hear that the Mailjet setup worked! If your initial question is resolved, you can click "Accept answer" to close this thread.

Regarding your new query on customizing the verification email using Azure Communication Services (ACS) instead of third-party providers, I’d recommend posting it as a separate question in the forum. This will help us, and other community members track it more effectively and provide a more focused and detailed response tailored to ACS integration.
