Solution 1Recommended

Manually Unassign Training in Microsoft Defender

Remove the training assignments directly from the Defender portal to stop ongoing automated notification emails.

Phishing simulations and their corresponding training assignments are managed as separate entities. Simply canceling a simulation campaign will not automatically remove the pending training assignments for users.

1
Log in to the Portal

Open your web browser and sign in to the Microsoft Defender portal using your administrator credentials.

2
Open Training Assignments

Navigate to the specific training assignment associated with the phishing simulation you recently canceled.

3
Filter the User List

Review the list of assigned users. You can filter the list to specifically identify users with failed email deliveries or those whose accounts have been deleted.

4
Remove the Training

Select the specific users or the entire assignment group, and click the option to remove or unassign the training. This action will immediately stop the system from sending further notification emails.

Frequently Asked Questions

Why are users still getting emails after I canceled the phishing simulation?

Phishing simulations and the resulting training assignments are processed as separate tasks. Canceling the simulation only stops the fake phishing emails from being sent, but any automated training triggered by that simulation must be unassigned manually.

Can I filter training assignments to only remove them for deleted users?

Yes, in the Microsoft Defender portal, you can filter the training assignment list by delivery status (such as failed deliveries) to specifically target and remove assignments for users whose accounts no longer exist.

What should I do if the option to remove the training is missing?

If you cannot see the option to unassign or remove the training, it is likely restricted by your organization's global training policies. You will need to consult your primary security administrator or contact Microsoft Support to modify these policies.
