Question details

The user needs to stop rapid, automated bot submissions and resolve "too many actions" errors on a public Microsoft Form without restricting access to only their organization.

Product: Microsoft Forms
Device & OS: not provided
Scenario: Collecting data via an anonymous, public survey.
Observed behavior: The public form is receiving a flood of fake responses from AI bots using stolen or fake emails, which triggers a "too many actions" error due to the rapid submission rate.

Before you start

Before proceeding, ensure you have access to your Microsoft 365 admin center or know how to contact your organization's IT administrator, as some diagnostic steps require administrative privileges.

Solution 1Recommended

Duplicate the Form to Generate a New Link

Creating a duplicate of your form generates a brand new form ID and URL, effectively stopping the bots that are targeting the old link.

Since Microsoft Forms does not feature a built-in CAPTCHA for public links, stopping a targeted bot attack often requires changing the entry point. Duplicating the form preserves your questions while resetting the submission URL.

Locate the affected form

Go to the Microsoft Forms portal (forms.microsoft.com) and find the survey currently receiving bot responses.

Copy the form

Click the 'More options' (three dots) button on the form's tile and select 'Copy'. This creates an exact duplicate with no previous responses.

Share the new link

Open the duplicated form, click 'Collect responses', and copy the new URL to share with your intended audience.

Close the old form

Open the original form, go to Settings, and uncheck 'Accept responses' to permanently block the bots from continuing their attack.

Solution 2

Request a Log Review via Microsoft 365 Support

If you cannot change the form link and the bot attack persists, escalate the issue to Microsoft's engineering team for backend investigation.

Frequently Asked Questions

Does Microsoft Forms have a CAPTCHA feature?

Currently, Microsoft Forms does not offer a built-in CAPTCHA feature to prevent bot responses on anonymous, public forms.

Why am I getting a 'too many actions' error in Forms?

This error typically occurs when a form receives an unusually high volume of automated submissions in a very short period, causing the server to temporarily throttle further actions.

Can I stop bots without making the form private to my organization?

The most effective workaround for a public form under bot attack is to duplicate the form to generate a new URL. You can then distribute this new link and disable responses on the compromised original form.

Could Power Automate be causing the automated responses?

While Power Automate can interact with Microsoft Forms, it only automates actions based on flows you or your team have actively configured. If no flow is set up, the submissions are likely external bots.
