The user encounters a database driver error when attempting to refresh external data sources in Microsoft Excel.

How to Fix Excel Database Driver Error When Refreshing External Data

Product: Microsoft Excel
Device & OS: not provided
Scenario: Refreshing external data connected via Power Query, Microsoft Query, or other database drivers.
Observed behavior: Excel displays a database driver error and fails to refresh the external data, often associated with a damaged driver, blocked network traffic, or Office update version 2211.

Before you start

Ensure your computer has an active internet connection and verify that the original external data source (such as a SQL server, web page, or local database) is accessible and running normally.

Solution 1Recommended

Troubleshoot Network and Connectivity Settings

Perform basic system checks and temporarily disable network security software to rule out connection blocks.

Often, a firewall or antivirus program may mistakenly block the required port traffic needed for Power Query or Microsoft Query to fetch data. Restarting your environment and testing the connection can quickly isolate whether the issue is local to your machine.

Restart Excel and your computer

Close all active Excel workbooks completely and restart your computer to clear any temporary background glitches.

Temporarily disable firewall and antivirus

Open your system's security settings and temporarily pause your antivirus and firewall protections. Return to Excel and attempt to refresh the external data.

Test on an alternative device

Open the same Excel workbook on a different computer connected to the same network. If the data refreshes successfully there, the issue is isolated to your original computer's configuration.

Troubleshoot Network and Connectivity Settings

Security Reminder: Remember to re-enable your firewall and antivirus software immediately after testing the data connection.

Frequently Asked Questions

What causes the Excel database driver error when refreshing external data?

This error is typically caused by corrupted Microsoft Query drivers, strict network firewall rules blocking port traffic, issues with the source data itself, or specific bugs found in certain Microsoft Office updates (such as version 2211).

How do I know if my firewall is causing the Excel refresh error?

You can isolate firewall issues by temporarily disabling your antivirus and Windows Defender Firewall. If the external data refreshes successfully while they are disabled, you will need to add an exception for Excel in your firewall settings.

Why did my external data stop refreshing after an Office update?

Certain Microsoft Office updates can introduce compatibility issues with specific database drivers. For example, version 2211 is known to cause this driver error. Reverting to a previous stable build like version 2210 or installing a newer patch usually resolves the problem.

Can repairing Office fix the Microsoft Query driver error?

Yes. Running an 'Online Repair' via the Windows Control Panel reinstalls all Office components, which replaces any missing, incompatible, or damaged database driver files that are causing the refresh to fail.
