Before you start

Add Microsoft 365 URLs to Antivirus Exceptions

Web protection features in antivirus software (especially Avast) often falsely flag and block Microsoft 365 login requests. Adding exceptions bypasses this block.

Overzealous antivirus web shields can interfere with secure connections between Chrome and Microsoft's servers. Whitelisting the official service URLs ensures your security software does not disrupt your workflow.

Open Antivirus Settings

Launch your antivirus dashboard (such as Avast Antivirus) from the system tray and navigate to the Settings or Preferences menu.

Locate Web Shield Exceptions

Find the Web Shield or Web Protection tab and look for a section labeled 'Exceptions', 'Allowed websites', or 'Exclusions'.

Add Microsoft URLs

Click 'Add Exception' and manually input the official URLs for your affected services, such as office.com, microsoft.com, onedrive.live.com, and teams.microsoft.com.

Restart Chrome

Save your newly added exceptions, completely close Google Chrome, and reopen it to test your Microsoft 365 access.

Quick Tip: If you are using a corporate device, your IT department may manage your firewall and antivirus settings. You might need to contact them to add these exceptions globally.

Frequently Asked Questions

Why does Chrome say 'Request is blocked' for Microsoft 365 but Edge works fine?

This usually indicates a local configuration conflict within Chrome. It can be caused by a specific browser extension, corrupted site cookies, or a third-party antivirus web shield that targets Chrome's web traffic while ignoring Microsoft Edge.

Can I bypass the blocked request by using Chrome's Incognito Mode?

Yes, testing in Incognito Mode is an excellent troubleshooting step. If the Microsoft 365 site loads successfully in Incognito Mode, the blocking issue is almost certainly caused by an active extension or corrupted cache data in your standard browsing profile.

What should I do if the error persists across multiple browsers and devices?

If you receive the 'Request is blocked' error regardless of the browser, network, or device you use, the issue is likely on Microsoft's end. It could be an account-specific restriction or a widespread server outage, meaning you should contact Microsoft Support or check the Microsoft 365 Service Health status.
