Fix Microsoft Defender Attack Simulation Training Link Redirection
Question details
Users are being redirected to the Microsoft Defender home page instead of their assigned Attack Simulation Training module when clicking the training link.

- Product
- Microsoft Defender
- Device & OS
- not provided
- Scenario
- Attempting to access a mandatory security training module assigned through Microsoft Defender.
- Observed behavior
- The provided training link fails to open the simulation module and unexpectedly redirects the user to the main Microsoft Defender dashboard.
Ensure you have the necessary administrator permissions in Microsoft 365 Defender to view and manage attack simulation campaigns and training assignments.
Verify Training Campaign and Assignment Status
Check if the training campaign has ended or the assignment has expired, which is the most common cause of link redirection.
Training links in Microsoft Defender are strictly tied to the lifecycle of the campaign. If the assignment duration lapses or the recipient is removed from the eligibility list, the links will default to the Microsoft Defender home page.
Log in to the Microsoft 365 Defender portal using your administrator credentials.
On the left navigation pane, go to Email & Collaboration and select 'Attack simulation training'.
Switch to the 'Simulations' or 'Training' tab to find the specific campaign assigned to the affected user.
Review the status and end date of the campaign to confirm if the training period has expired or if the recipient remains eligible.

Consult Microsoft Support and Q&A
If the campaign is active but links still redirect, reach out to Microsoft specialists for advanced troubleshooting.
Manage Your Security Training Documents with WPS Office
While Microsoft Defender handles your attack simulation training, you can use WPS Office as a lightweight, free alternative to Microsoft Office for creating, documenting, and sharing your organization's security policies and training materials.
- 1. Download the Installer: Visit the official WPS Office website and click the free download button.
- 2. Install the Software: Run the downloaded installer and follow the on-screen instructions to complete the setup.
- 3. Open and Edit Documents: Launch WPS Office and instantly open your existing Microsoft Office files to start managing your security documentation.
