How to fix Microsoft 365 if it is not working

Still can't connect even though the servers are green? The Microsoft 365 lag is likely on your end. Run through this quick checklist to get back online:

• Clear Browser and Application Cache: If you are using the web version of Microsoft 365, clear your browser's cache and cookies, or try accessing the portal via an Incognito or Private browsing window. For desktop applications like Microsoft Teams or Outlook, clearing the local app cache folder can quickly resolve persistent login loops, blank screens, and synchronization errors.
• Flush DNS and Verify Network Settings: Connectivity issues can occur if your local network fails to properly resolve Microsoft's server IP addresses. You can fix this by flushing your DNS cache (open Command Prompt as administrator and run 'ipconfig /flushdns'), or by temporarily switching your device's DNS servers to a reliable public provider like Google (8.8.8.8) or Cloudflare (1.1.1.1).
• Check Account Authentication and Licensing: Local authentication failures can often masquerade as global outages. Ensure your Microsoft 365 subscription is active by logging into your Microsoft account portal. If you are on a corporate network, contact your IT administrator to verify that your Azure Active Directory account credentials are valid and have not been locked or restricted due to security policies.
