Question details

The user's legitimate questionnaire, which collects participant details like names and university programs, is being incorrectly blocked by the system's anti-phishing filter.

Product: Microsoft Forms
Device & OS: not provided
Scenario: Creating and sharing a legitimate data collection questionnaire using a personal Microsoft account.
Observed behavior: The system automatically flags and blocks the form as a phishing attempt, preventing the owner from collecting responses or easily deleting the form.

Before you start

Review your form's questions to ensure there are no requests for highly sensitive information or keywords (like 'password' or 'account') that commonly trigger security filters.

Solution 1Recommended

Report the False Positive and Recreate the Form

Because the automated phishing algorithm cannot be manually bypassed by personal account users, you must report the error and adjust your form's content to prevent further blocking.

Microsoft Forms uses an automated screening algorithm to protect users from malicious data collection. Personal accounts have strict thresholds, and unfortunately, owners cannot directly adjust or turn off these filters.

Report to Microsoft

Click the 'Report' or 'Contact Support' link provided within the phishing warning message in your blocked Microsoft Form to alert the support team of the false positive.

Identify Trigger Keywords

Review your questionnaire for wording or layouts that typically trigger filters, such as overly broad requests for personal identification, financial data, or account credentials.

Create a Revised Form

Click 'New Form' on the Microsoft Forms homepage and recreate your questionnaire using alternative phrasing to bypass the automated screening algorithm.

Delete the Blocked Form

If you are unable to delete the flagged form from your dashboard, open the blocked form, delete all individual questions one by one, and then attempt to delete the form itself.

Enterprise Accounts: If you are using a work or school account, your IT administrator can review and unblock the form from the Microsoft 365 Defender portal.

Frequently Asked Questions

Why does Microsoft Forms flag my university questionnaire as phishing?

Microsoft Forms uses an automated screening algorithm scanning for patterns associated with malicious data collection. Asking for combinations of specific personal details may trigger a false positive, even if the intent is legitimate.

Can I manually unblock a form flagged for phishing?

No, personal account users cannot directly bypass or adjust the phishing screening algorithm. You must report the issue to Microsoft as a false positive or create a new form with adjusted content.

How do I delete a Microsoft Form that is locked due to phishing?

If the system prevents you from deleting the entire form directly from the dashboard, you can bypass this restriction by opening the form, deleting all the individual questions inside it first, and then deleting the form.

Do enterprise accounts have the same phishing filters as personal accounts?

Both account types use phishing protection, but enterprise administrators have more control. Admins can review blocked forms internally through the Microsoft 365 Defender portal and manually unblock them, whereas personal accounts rely entirely on Microsoft's automated system.
