How to Fix SharePoint Sign-In Error: Sign-In Is Not Working Right Now

Product: Microsoft SharePoint
Device & OS: not provided
Scenario: Attempting to sign in to SharePoint, Microsoft Teams, or access shared folders via OneDrive.
Observed behavior: An error page appears stating 'Sign-In Is Not Working Right Now' along with a correlation ID, timestamp, and an unknown issue type.

Before you start

Before troubleshooting, take a screenshot of the error message to capture the exact correlation ID and timestamp, as your IT administrator or Microsoft Support will need this information to investigate the backend logs.

Solution 1

Bypass the Error by Reloading the Session

A quick workaround that sometimes restores access temporarily without requiring administrative intervention.

Close the error page

Simply close the browser tab or window where the 'Sign-In Is Not Working Right Now' error is displayed.

Return to the SharePoint URL

Open a new tab and navigate back to the original SharePoint or Teams URL. In many cases, the background authentication has actually succeeded, and you will bypass the error on the second attempt.

Solution 2Recommended

Report Diagnostic Information to the Microsoft 365 Administrator

Since this is typically a backend service or identity configuration issue, escalating it to your IT admin with the right details is the most effective permanent solution.

Frequently Asked Questions

What is a correlation ID in the SharePoint error?

A correlation ID is a unique alphanumeric tracking code generated by Microsoft servers when an unexpected error occurs. IT administrators and Microsoft Support use this ID to trace the exact moment of failure in the backend system logs.

Why does closing the error page sometimes fix the login?

Closing the page and returning to the SharePoint site forces your browser to re-evaluate your session token. Sometimes the background authentication actually succeeds despite the error page rendering, allowing access on subsequent attempts.

Can I access my SharePoint files if I cannot sign in?

If you previously synced your SharePoint document libraries or Teams files to your computer using the OneDrive desktop client, you can still access the offline copies of your files directly from File Explorer (Windows) or Finder (Mac).

Does clearing browser cache fix the 'Sign-In Is Not Working Right Now' error?

Occasionally, yes. If the issue is caused by a corrupted session cookie rather than a backend Microsoft 365 outage, clearing your browser cache and cookies or trying an Incognito/Private browsing window can force a fresh authentication prompt.
