Question details

The user is unable to distribute a form or quiz because the system flags it for requesting personal or sensitive data, even though it only contains standard exam questions.

Fix Microsoft Forms Blocked for Requesting Sensitive Information

Product: Microsoft Forms
Device & OS: not provided
Scenario: Attempting to share or distribute an online quiz or exam to users.
Observed behavior: Microsoft Forms automatically blocks the form and displays a warning stating that the quiz cannot be distributed because it requests personal or sensitive information.

Before you start

Ensure you know who your organization's Microsoft 365 IT administrator is, as resolving automated phishing blocks usually requires administrative access to the Microsoft 365 Defender portal.

Solution 1Recommended

Request a Microsoft 365 Administrator to Unblock the Form

Since the form was restricted by automated phishing and sensitive data filters, a tenant administrator must review and manually unblock it.

Microsoft uses automated machine learning to protect users from malicious data collection. Occasionally, standard quiz questions trigger a false positive, causing the form to be locked.

Contact your IT Admin

Reach out to your organization's Microsoft 365 administrator and provide them with the link to your blocked form.

Admin Review

The administrator must log into the Microsoft 365 Defender portal and navigate to the Alerts or Action center to find the forms detected as potential phishing.

Unblock the Form

Once the admin verifies the form is legitimate, they can select the option to unblock the form and restore your ability to distribute it.

Administrator Guidance: Administrators can find specific unblocking options under Microsoft's official guidance for 'Reviewing and unblocking forms or users detected and blocked for potential phishing'.

Solution 2

Refresh the Page and Re-upload

If the sensitive information error transiently appears during the upload or saving process, refreshing the session can sometimes clear the warning.

Solution 3

Modify Questions to Bypass the Phishing Filter

If you cannot reach an IT administrator immediately, altering the wording of your questions may prevent the automated filter from flagging your quiz.

Frequently Asked Questions

Why did Microsoft Forms block my quiz as phishing?

Microsoft Forms utilizes automated machine learning algorithms to scan for malicious data collection. Sometimes, standard exam questions contain keywords that trigger a false positive, causing the system to preemptively lock the form.

Can I unblock the Microsoft Form myself without an admin?

Usually, no. In most enterprise or educational environments, only a Microsoft 365 administrator has the necessary permissions in the Microsoft 365 Defender portal to review and unblock a form flagged for sensitive information.

How long does it take for a form to be unblocked?

Once your administrator reviews the flagged form and selects the unblock option in the admin center, the form is typically restored and available for distribution within a few minutes.

How can I prevent my forms from being blocked in the future?

Avoid using vocabulary commonly associated with personal identifiable information (PII) or login credentials in your quiz questions. If you must use them for testing scenarios, try to alter the context or provide clear disclaimers.
