not provided
Scenario
Configuring language settings for localized Attack Simulation Training campaigns.
Observed behavior

Solution 1Recommended

Review Simulation Automations and Payload Settings

Check the simulation automations and specific payload settings to ensure the correct language is applied to all components of the phishing campaign.

In Microsoft Defender Attack Simulation Training, payloads and training modules are configured separately. If the initial phishing email remains in English while the rest of the content is in your preferred language, the payload language might not be properly aligned with the training language, or the specific payload may lack a translation.

1
Access Attack Simulation Training

Log in to the Microsoft 365 Defender portal and navigate to 'Email & collaboration', then select 'Attack simulation training'.

2
Review Simulation Automations

Go to the 'Automations' tab and review the specific simulation automation that is deploying the English emails.

3
Check Payload Language

Edit the simulation or automation to ensure the selected payload is available and explicitly configured for your target language (e.g., German).

4
Verify Language Fallbacks

Consult the official Microsoft simulation automation documentation to verify how the system handles language fallbacks when a localized version of a payload is unavailable.

Review Simulation Automations and Payload Settings
Language Fallback Behavior: If a specific payload or training module is not natively localized in your selected language, Microsoft Defender may default to displaying it in English.

Frequently Asked Questions

Why is the first email in the Microsoft phishing simulation still in English?

This usually happens because the specific payload selected for the simulation does not have a translation available in your chosen language, causing the system to fall back to the default English version.

Can I create custom localized payloads in Microsoft Defender?

Yes, administrators can create custom payloads and manually draft the email content in their preferred language to ensure the initial phishing email matches the users' native language.

Does changing the Microsoft 365 admin portal language change the simulation language?

No, the language of the Attack Simulation Training emails and training modules is determined by the specific settings configured within the simulation campaign and the user's regional settings, not the administrator's portal language.
