Open the private provider’s page in an Edge InPrivate window first; if the CAPTCHA appears there, disable an interfering extension or clear the affected site’s stored data in the normal window.
1. Test in InPrivate
- In Edge, select Settings and more (…).
- Select New InPrivate window.
- Open the provider’s website, sign in if necessary, and return to the message form.
InPrivate does not retain the normal window’s cookies and temporary site data after the session, making this a useful first test.^1^
- If the CAPTCHA appears: continue with steps 2–4 in the normal Edge window.
- If it remains blank: skip to step 5.
2. Confirm JavaScript is allowed
CAPTCHA controls normally require browser scripting.
- Go to Settings and more (…) → Settings.
- Open Privacy, search, and services → Site permissions → All permissions.
- Select JavaScript.
- Confirm Allowed (recommended) is enabled, then reload the form.^2^
If the setting is controlled by your organization, contact its administrator rather than trying to override the policy.
3. Allow the site’s cookies
A CAPTCHA may load content from a different site. Blocking third-party cookies or using strict privacy protection can therefore prevent parts of a page from displaying correctly.^3^
- Open Settings → Privacy, search, and services → Cookies.
- Ensure Allow sites to save and read cookie data (recommended) is enabled.
- If Edge displays a prompt asking whether another site may access cookies and site data, allow it for this provider and reload the page. Such temporary permission lasts 30 days and can be removed later.^4^
Avoid broadly weakening privacy settings when a site-specific allowance works.
4. Check extensions
Ad blockers, privacy tools, script blockers, and security extensions can interfere with page components.
- Select Extensions → Manage extensions.
- Temporarily turn off relevant extensions.
- Reload the provider’s form.
- If the CAPTCHA appears, re-enable extensions individually to identify the conflicting one.^5^
Keep the extension disabled only on that provider’s site if it supports per-site access controls.
5. Clear cached content and update Edge
- Select Settings and more → History → Open history page → Delete browsing data.
- Set Time range to All time.
- Select Cached images and files, then Clear now.
- Open Settings → About Microsoft Edge and install any offered update.
- Close and reopen Edge, then test again.^6^
Clearing cookies as well will sign you out of websites, so start with cached files only.
6. Determine whether it is the website or Edge
Open the same form in another browser:
- Blank in every browser: contact the private provider. The website or its CAPTCHA service likely requires investigation by its owner.
- Works elsewhere but remains blank in Edge: in Windows 11, close Edge and go to Start → Settings → Apps → Installed apps → Microsoft Edge → Modify → Repair. Administrative rights and an internet connection are required; Microsoft states that browser data and settings should not be affected.^6^
If repair does not resolve it, submit a report through Edge → Settings and more → Help and feedback → Send feedback, including the website name and a screenshot of the blank CAPTCHA area.
