Copilot: can’t connect email/health

Question

Connecting to any of the listed options, ie gmail/health apps, ends with blank screen: copilot.Microsoft.com. Using iPhone but same on PC. Tried reloading app, web only, different browsers, settings. Microsoft Support ended by sending me here

Answer 1

Opening the connector in a normal browser tab and checking whether any URL appears at the top is the safest first step. If the URL stops loading or stays on copilot.microsoft.com, the redirect is being blocked. Testing on another network (mobile vs Wi‑Fi) helps show whether the network is blocking the redirect. On iPhone Safari, Prevent cross‑site tracking can block the OAuth window, so Chrome or relaxing that setting often fixes it. On PC, extensions or a VPN can block the same redirect and cause a blank screen.

Answer 2

1. In Copilot, open Profile > Connectors and try connecting the service again from there. For first-time setup, select Connect, then Continue to …, and complete the authorization flow for the target service.
2. If the connection ends on a blank copilot.microsoft.com page in a browser, enable third-party cookies and retry. This is required for Copilot license validation in web apps and can affect sign-in/connection flows.
   • Edge: Settings and More > Settings > Cookies and site permissions > Manage and delete cookies and site data > set Block third-party cookies to Off.
   • Chrome: Settings > Privacy and security > select Allow third-party cookies.
   • Firefox: Settings > Privacy & Security > under Enhanced Tracking Protection, select Custom and ensure Cookies is unchecked.
   • Safari (MacOS): Settings > Privacy > uncheck Prevent cross-site tracking; in Advanced, ensure Allow-privacy-preserving measurement of ad effectiveness and Block all cookies are unchecked.
3. If using a personal Microsoft account, ensure the Microsoft account used to sign in to Copilot matches the account used for OneDrive or Outlook. If they do not match, Copilot cannot retrieve content.
4. Since the issue occurs on both iPhone and PC, run the built-in connectivity check on Windows:
   • Open Get Help.
   • Search for Copilot connectivity troubleshooter.
   • Run it to check for firewall rules or other connection blockers.
5. If Copilot in Edge or the web still shows a blank page, verify basic service reachability:
   • Confirm the device has an active internet connection.
   • If the Copilot pane shows blank/error/refresh behavior after retries, check the Microsoft 365 Service health status page for an outage and retry later.
6. If the connector still fails after these checks, use the in-product connector flow again after refreshing the page/browser session.
