Device & OS: not provided
Scenario: Attempting to launch and log into the Microsoft Copilot application.
Observed behavior: The application repeatedly switches back and forth between the sign-in screen and the Copilot chat interface, blocking users with eligible access from actually using the tool.

Report the Issue to the Microsoft Community

Since this reloading loop is often tied to backend authentication bugs or account synchronization errors, reporting it with your specific details to Microsoft is the most effective path to a resolution.

Microsoft actively monitors community forums for widespread authentication bugs. Providing your specific account and environment details helps their engineering team identify and patch the root cause of the reloading loop.

Gather your diagnostic information

Note down your account type (e.g., Enterprise or Personal), your current Office version, your Copilot license status, device details, and a brief description of the sign-in loop symptoms.

Visit the official Microsoft forums

Navigate to the Microsoft 365 Copilot community page (techcommunity.microsoft.com) or the Microsoft Q&A portal (learn.microsoft.com/en-us/answers/questions/ask/).

Post your question

Create a new post detailing your issue. Make sure to include the tag 'Microsoft Copilot for Microsoft 365' so that it reaches the correct support engineers.

Check for ongoing service outages: Before posting, take a quick look at the Microsoft 365 Service Health dashboard to see if there is already a known ongoing authentication outage affecting Copilot.
