I have Microsft 365 personal. Suddenly, today, CoPilot will not open

Open a Safari private window and sign in at copilot.microsoft.com with the same personal account; if it redirects to copilot.com, use that updated Copilot experience instead.

Microsoft is moving personal accounts to the updated Copilot web app at different times. A redirect to copilot.com means the account has moved or is completing that move; if it remains at copilot.microsoft.com, continue there for now.^1^

If the page remains blank

1. Return to a normal Safari window and refresh the page.
   Private browsing is useful for checking the account transition and bypassing stored session data, but it can restrict cookies. Therefore, failure only in a private window does not establish a subscription problem.
2. Test Safari’s cookie settings temporarily:
   • Select Safari > Settings > Privacy.
   • Clear Prevent cross-site tracking.
   • Select Advanced.
   • Under Privacy, ensure both Allow privacy-preserving measurement of ad effectiveness and Block all cookies are unchecked.
   • Close Settings, reload Copilot, and sign in again.
   Microsoft documents these Safari settings because Copilot license validation in Microsoft 365 web apps requires third-party cookies.^2^ Privacy note: Turning off cross-site tracking protection reduces Safari’s privacy protections. If it does not resolve the blank page, restore the original settings. Alternatively, use a separate supported browser for Copilot.
3. Remove only Microsoft/Copilot website data if Safari is still blank:
   • Open Safari > Settings > Privacy > Manage Website Data.
   • Search for Microsoft, Office, or Copilot entries.
   • Remove those entries, select Done, and sign in again.
   This is a browser-session troubleshooting step; it signs you out of the affected Microsoft sites. Removing Copilot site cookies and signing in again is also an established Microsoft Q&A resolution for web-page errors.^3^

Isolate Safari from an account problem

• Open Copilot in the current version of Microsoft Edge or Google Chrome and sign in with the same Microsoft 365 Personal account. Safari, Edge, Chrome, and Firefox are supported for Microsoft 365 web experiences.^4^
• If it works there, the problem strongly points to Safari’s stored website data, privacy settings, an extension, or its current version—not conclusively to every subscription feature.
• If it is blank in every supported browser, check that the profile shown in the upper-right corner is the personal account that owns the subscription. Microsoft recommends switching accounts when the active account does not have the applicable Copilot entitlement.^2^
• Update macOS/Safari if they are not current. Microsoft 365 is designed for currently supported software configurations.[^5^](https://support.microsoft.com/en-us/accounts-billing/subscriptions/[Subscription ID] "Microsoft 365 system requirements | Microsoft Support")

The public consumer status feed currently reports Microsoft Copilot and Microsoft 365 Consumer as operational, so this does not presently appear to be a broad consumer outage.^6^

If it still fails everywhere

Persistent failure in Safari, Edge, and Chrome can indicate an account or licensing condition that requires Microsoft Support to inspect. As a Microsoft 365 Personal user, use the official Microsoft Support contact route. Include:

• That Copilot shows a blank page in multiple browsers
• The approximate time the problem began
• Your macOS and Safari versions
• A screenshot of the blank page
• Whether either Copilot address redirected to the updated experience

If the Copilot menu becomes available, optionally select … > Send feedback > Report a problem.^1^
