Question details

The user needs to resolve a network connection error that prevents Microsoft 365 from renewing, which began after installing and uninstalling Palo Alto GlobalProtect VPN.

Product: Microsoft 365
Device & OS: not provided
Scenario: Attempting to renew or verify a Microsoft 365 subscription on a computer that previously had GlobalProtect VPN installed.
Observed behavior: Microsoft 365 displays a renewal error message stating there is no network connection, even though the user has already uninstalled and deleted the VPN application.

Before you start

Verify that your computer has a working internet connection by browsing a few websites, and restart your device to clear out any temporarily cached network routing rules.

Solution 1Recommended

Remove Leftover GlobalProtect Network Settings

Standard uninstallation may leave behind hidden virtual network adapters or proxy settings that block Microsoft 365 from communicating with activation servers.

VPN software often alters deep system-level network configurations. To restore normal connectivity for Microsoft 365, you need to ensure all traces of these custom adapters and routing rules are thoroughly removed.

Consult Palo Alto Support

Visit the Palo Alto Networks community forums to find specific manual uninstallation scripts or official steps for entirely removing leftover GlobalProtect registry keys and network drivers.

Reset Network Settings

If you are on Windows, navigate to Settings, select Network & Internet, go to Advanced network settings, and execute a Network Reset to reinstall your default network adapters.

Verify Proxy Configurations

Open your computer's proxy settings and ensure that no residual VPN proxy servers are enabled. Set the configuration to automatically detect settings.

System Reboot Required: You must restart your computer after making any changes to network adapters or registry settings to ensure the changes take effect.

Solution 2

Verify Subscription via Microsoft 365 Admin Center

Confirming your subscription status centrally can help isolate whether the issue is purely a local network block or an actual billing failure.

Solution 3

Use Microsoft 365 Web Apps Temporarily

While investigating the desktop client network issue, you can continue your work without interruption using the browser-based version of Microsoft 365.

Frequently Asked Questions

Why does Microsoft 365 say there is no network connection even after uninstalling my VPN?

Enterprise VPN software like Palo Alto GlobalProtect modifies system-level network adapters and routing tables. A standard uninstallation may leave these hidden components behind, which intercepts or blocks the specific network traffic Microsoft 365 uses to reach its licensing servers.

How can I capture the exact Microsoft 365 error code for support?

When the renewal failure prompt appears, look for a 'Details' or 'More information' link within the dialog box. Take a full screenshot of this expanded window, ensuring any alphanumeric error codes are clearly visible to share with Microsoft Support.

Can I still edit my documents if the Microsoft 365 desktop app won't connect?

Yes, as long as your subscription is still valid on the server side, you can log in to microsoft365.com using your web browser to create and edit documents via the cloud-based versions of Word, Excel, and PowerPoint.
