Question details

Users need to know how to return to Microsoft Defender Attack Simulation training after closing their browser, while administrators need guidance on restricting user access to other tenant areas from the assignments page.

How to Manage Microsoft Defender Training Assignments and Portal Access Restrictions

Product: Microsoft Defender
Device & OS: not provided
Scenario: A user accidentally closes the training browser session and needs to resume, or an admin wants to enforce strict access controls to prevent users from navigating to unauthorized tenant areas.
Observed behavior: Users are unable to locate the link to resume their assigned training, and administrators observe that default portal pages may expose links to Azure resources or other tenant areas.

Before you start

Ensure you have the necessary administrator permissions in the Microsoft 365 Defender portal to review and modify user roles before attempting to restrict access.

Frequently Asked Questions

Why can't users access the training link directly from their notification email?

If users cannot access the training directly from the notification email, they may be experiencing browser caching issues, or the temporary link might have expired. Advise them to navigate directly to https://security.microsoft.com/trainingassignments instead.

Can I completely hide the Azure resources link from end-users on the assignments page?

The visibility of additional resources is largely controlled by the default Microsoft 365 service design and the user's assigned roles. Ensure the user does not have elevated permissions. If standard role-based access control does not hide the links, you must escalate the request to Microsoft Support.

How do I verify if a user has completed their assigned Attack Simulation training?

Administrators can check training completion status by navigating to the Microsoft 365 Defender portal, going to 'Email & collaboration', selecting 'Attack simulation training', and reviewing the metrics under the specific simulation's report tab.
