How to Fix OneDrive Error Code 2606 After Unlinking an Account

Product: OneDrive
Device & OS: Windows
Scenario: Reconnecting, syncing, or signing back into the OneDrive desktop application after an account has been unlinked or the network environment has changed.
Observed behavior: OneDrive fails to connect or sync, displaying error code 2606. A standard application reset of OneDrive does not resolve the connectivity issue.

Before you start

Ensure you have your Microsoft account login credentials ready, as you will need to sign back into OneDrive. Additionally, verify that your computer has a stable internet connection before modifying system network configurations.

Solution 1Recommended

Reset Windows Internet and Proxy Settings via Run Dialog

This is the most effective method for resolving Error 2606, as it clears problematic system-level network and proxy configurations that block OneDrive from communicating with Microsoft servers.

OneDrive relies on Windows internet settings to establish a secure connection. If these settings become corrupted after a network change, OneDrive will throw error 2606. Resetting them forces Windows to rebuild a clean connection path.

Sign out of your Microsoft Account

Right-click the OneDrive cloud icon in your system tray, click the gear icon for 'Settings', navigate to the 'Account' tab, and click 'Unlink this PC'.

Open the Windows Run dialog

Press the Windows Key + R simultaneously on your keyboard to open the Run dialog box.

Execute the reset command

Type 'RunDll32.exe InetCpl.cpl,ResetIEtoDefaults' (without quotes) into the Run box and press Enter.

Confirm the reset options

A reset window will appear on your screen. Proceed with the reset, making sure NOT to select or check the 'Delete personal settings' checkbox.

Reopen and sign in to OneDrive

Launch the OneDrive application from your Start menu and sign back in using your Microsoft account credentials to resume syncing.

Reset Windows Internet and Proxy Settings via Run Dialog

Organizational Accounts: If your device or Microsoft account is managed by an organization, check with your IT administrator to ensure there are no network-wide proxy policies blocking the connection.

Solution 2

Temporarily Disable Windows Web Proxy

Disabling the manual web proxy ensures that third-party network routing isn't interfering with OneDrive's server communication.

Frequently Asked Questions

What exactly causes OneDrive Error 2606?

Error 2606 is typically triggered by improper Windows network configurations. This often happens due to incorrect proxy settings, leftover cached connection data after unlinking an account, or strict organizational network policies.

Will running the ResetIEtoDefaults command delete my saved browser passwords?

No. As long as you run the command and leave the 'Delete personal settings' checkbox unselected, your browser history, bookmarks, and saved passwords will remain fully intact while the underlying connection settings are reset.

Why didn't simply resetting the OneDrive app fix error code 2606?

Resetting the OneDrive app only clears the application's local cache and internal sync state. Error 2606 is rooted in the Windows operating system's network routing and proxy settings, which require a system-level configuration reset to resolve.
