Update the IPv4 DNS Server Addresses

Switching your computer's default DNS server to a reliable public DNS like Cloudflare can resolve routing issues that block Office.com.

Internet Service Providers (ISPs) sometimes experience DNS server outages or routing glitches that block specific domains like Office.com. Switching to a secure, public DNS bypasses these local ISP routing issues.

1
Open Network Connections

Press the Windows Key + R to open the Run dialog box. Type ncpa.cpl and press Enter to launch the Network Connections window.

2
Access Adapter Properties

Right-click your active network adapter (the Wi-Fi or Ethernet connection you are currently using) and select Properties from the context menu.

3
Modify IPv4 Settings

In the list of items, locate and double-click Internet Protocol Version 4 (TCP/IPv4).

4
Enter New DNS Addresses

Select the option Use the following DNS server addresses. Enter 1.1.1.1 as the Preferred DNS server and 1.0.0.1 as the Alternate DNS server.

5
Save and Restart

Click OK on both windows to apply the settings. Restart your computer and try loading Office.com again.

Frequently Asked Questions

Why does Office.com load on mobile data but not on my home Wi-Fi?

Your mobile data connection uses a different network provider and DNS server than your home internet. If your home network's specific DNS server is failing to resolve the Office.com address, the site will only load when you switch to mobile data or a VPN.

What is Cloudflare DNS (1.1.1.1)?

Cloudflare DNS is a secure, fast, and privacy-focused public DNS resolver. By changing your computer's DNS to 1.1.1.1, you bypass your Internet Service Provider's default DNS, which is often the cause of specific websites failing to load.

Will changing my DNS settings affect my computer's security?

No, changing to a reputable public DNS like Cloudflare (1.1.1.1) or Google (8.8.8.8) is completely safe. In many cases, it actually enhances your browsing security and speeds up website loading times.

Do I need to change the DNS on my router or just my computer?

Changing the DNS on your computer is usually sufficient for resolving local access issues. However, changing it on your router applies the new DNS settings to every device connected to your home network, which can be useful if multiple devices cannot access Office.com.
