Fix outlook-my.sharepoint.com Refused to Connect in Microsoft Forms
Question details
Users encounter a connection refusal error when attempting to view embedded SharePoint videos within Microsoft Forms.
- Product
- Microsoft Forms
- Device & OS
- not provided
- Scenario
- Viewing a Microsoft Form containing embedded videos after recent browser updates.
- Observed behavior
- An error message stating 'outlook-my.sharepoint.com refused to connect' appears in the embedded frame on Chrome and Edge, while the video continues to load correctly in Firefox.
Verify if the issue persists across different web browsers. Since this error is known to specifically affect Chromium-based browsers like Google Chrome and Microsoft Edge, try accessing the form in Mozilla Firefox to confirm the nature of the issue.
Contact Microsoft 365 Support for Backend Investigation
Because this issue relates to Chromium browser updates affecting embedded SharePoint frames, it typically requires a backend resolution directly from Microsoft.
Recent updates to Chromium-based browsers have altered how cross-site data and embedded frames are handled. This can cause SharePoint resources to be blocked within Microsoft Forms.
Individual end-users cannot fix backend frame-embedding restrictions. The most effective path to a permanent fix is having an administrator escalate the issue to the Microsoft 365 support team.
Reach out to your organization's IT department or the assigned Microsoft 365 administrator who manages your company tenant.
Instruct the administrator to log into the Microsoft 365 admin center using their administrative credentials.
Navigate to the support section and submit a new service request detailing the 'outlook-my.sharepoint.com refused to connect' error. Mention that it specifically affects Chrome and Edge after recent updates.
Use Mozilla Firefox to View Forms
As a temporary workaround, you can use a non-Chromium browser where the embedded SharePoint frame continues to function normally.

Frequently Asked Questions
Why does the 'outlook-my.sharepoint.com refused to connect' error only happen in Chrome and Edge?
Recent security and privacy updates in Chromium-based browsers (like Google Chrome and Microsoft Edge) have changed how third-party cookies and embedded iframes are handled. These strict policies can inadvertently block embedded SharePoint content, whereas Mozilla Firefox uses a different rendering and security engine that may not trigger this block.
Can I fix the Microsoft Forms embedded video error myself by changing browser settings?
While you can try allowing third-party cookies or disabling tracking prevention for the specific SharePoint URL in your browser settings, these local tweaks often fail if the issue stems from backend configuration mismatches caused by recent updates. Escalating to your IT administrator is the most reliable solution.
Will clearing my browser cache resolve the SharePoint connection error?
Clearing your browser cache and cookies is a good standard troubleshooting step, but it is unlikely to fix this specific issue if it was triggered by a recent browser update altering iframe security policies. However, it takes only a minute and is worth trying before contacting your IT administrator.
