How to Fix Power Query Security Warning About Blocked Active Content in Excel
Question details
The user is trying to clear a persistent security warning in Excel Power Query stating that the browser has restricted active content.
- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Using Power Query to access, refresh, or manage external data sources.
- Observed behavior
- A warning about restricted active content repeatedly appears and blocks functionality, even after the user manually selects the option to allow blocked content.
Save your current workbook and ensure you have your IT support contact information handy, as organizational security policies or group policies might be enforcing this restriction.
Reset Default Browser Settings and Restart Excel
Since Power Query relies on underlying Windows web components to authenticate and fetch data, resetting your browser to its default settings can clear incorrect security restrictions.
Excel Power Query often utilizes Internet Explorer or Microsoft Edge WebView components in the background. Corrupted security zones or cached policies in these browsers can trigger persistent active content warnings.
Open your system's default web browser or Internet Explorer/Edge and navigate to the main Settings menu.
Find the 'Reset settings' or 'Restore settings to their default values' option, usually located under Advanced settings.
Confirm the reset action. This will clear customized security zones, temporary files, and cached web settings.
Close the browser, completely exit Microsoft Excel, reopen your workbook, and reload your Power Query data source to see if the warning is resolved.
Request Microsoft 365 Support via Your IT Administrator
If browser resets fail, strict organizational policies might be blocking the active content. An IT administrator must escalate this issue to Microsoft Support.

Frequently Asked Questions
Why does Excel Power Query rely on browser settings for security?
Power Query uses underlying Windows web components (like Internet Explorer or Edge WebView) to authenticate and connect to external web data sources. Therefore, Windows browser security zones and restrictions directly affect what active content is permitted to run during a query.
What exactly is 'active content' in the context of this warning?
Active content typically refers to scripts, ActiveX controls, or interactive web elements used during the data connection and authentication process. The operating system often flags these elements as potential security risks if they are not explicitly trusted.
Can I bypass this organization-level warning without IT administrator rights?
If the active content restriction is enforced by a local Group Policy or a central Microsoft 365 security setting, you cannot bypass it yourself. You must request your IT department to adjust the policy or open a support ticket on your behalf.
