If you're getting a "Word unable to open data source" error, it usually means that Word is having trouble connecting to the source of data for a mail merge or other data-driven feature.
1. Check Data Source File
Ensure Accessibility: Verify that the data source file (such as an Excel spreadsheet or Access database) is in a location accessible to Word and not moved, renamed, or deleted.
Verify Format: Make sure the file format is compatible with Word and not corrupted.
2. Verify File Path
Check File Path: Ensure the file path to the data source is correct and hasn’t changed. If the file was moved, you might need to update the path in Word.
3. Confirm Data Source Compatibility
Data Format: Ensure that the data source file is in a format that Word supports and that it’s not encrypted or password-protected if that’s not supported by your current settings.
4. Re-establish Connection
Re-Link Data Source: In Word, go to the Mailings tab, click Select Recipients, and choose Use an Existing List. Browse to the data source and reselect it.
5. Update Office
Check for Updates: Make sure your version of Word is up to date. Sometimes updates include fixes for known issues.
6. Repair Office
Office Repair Tool: Use the built-in Office repair tool to fix potential issues with your installation of Word.
7. Check Permissions
File Permissions: Ensure you have the necessary permissions to access the data source file.
