How to Fix 'Request Blocked' Error When Activating Office 2021
Question details
The user needs to resolve a 'Request Blocked' error that occurs when trying to activate Office Home & Business 2021 and access Microsoft services.
- Product
- Microsoft Office 2021
- Device & OS
- not provided
- Scenario
- Activating Office 2021 or signing into Microsoft services like Office.com/setup and email.
- Observed behavior
- A 'Request Blocked' error message appears, preventing sign-in across multiple browsers (Firefox, Chrome) and blocking access to activation servers, email, and support pages.
Before troubleshooting, ensure you have your Microsoft account credentials ready and verify that your internet connection is stable without any strict firewall rules applied.
Adjust Network, VPN, and Proxy Settings
Since the error spans multiple browsers and services, a network-level block or VPN is likely causing the issue.
Microsoft's security servers will occasionally block certain IP addresses or traffic routing methods. Disabling third-party network filters can often clear the block.
If you are using a Virtual Private Network (VPN), temporarily disconnect it. Microsoft servers may block certain VPN IP ranges for security reasons.
Open your computer's network settings and disable any manual proxy servers that might be routing your traffic incorrectly.
Try connecting your computer to a different network, such as a mobile hotspot, to rule out restrictions imposed by your local ISP or router firewall.
Use Private Browsing or an Alternate Device
Corrupted browser cache or device-specific security software can trigger request blocks on Microsoft websites.
Contact Microsoft via an Alternate Account
If the block applies strictly to your specific Microsoft account profile, you may need official support intervention.
Switch to WPS Office for a Hassle-Free Experience

Frequently Asked Questions
Why does Microsoft say my request is blocked when activating Office 2021?
This error typically occurs when Microsoft's security servers detect suspicious traffic, block your IP address due to a VPN, or when browser cookies conflict with the sign-in redirect process.
How can I contact Microsoft if the support page is also blocked?
If you cannot access the support page on your primary setup, try using a completely different internet connection (like mobile data) and sign in with an alternative Microsoft account to request support for your main account.
Does clearing the browser cache fix the Office activation block?
Yes, in some cases. Corrupted session data can cause infinite redirect loops resulting in a blocked request. Clearing your browser's cookies and cache or using an incognito window can resolve this specific trigger.
