    Issue

    When connecting to a Microsoft Access or Microsoft Excel file, you may see the following error:

    Database error 0x80004005: Unrecognized database format '[database-name]'. 
    Unable to connect to the server. Check that the server is running and that you have access privileges to the requested database.

    Environment

    • Tableau Desktop
    • Microsoft Access or Microsoft Excel file

    Resolution

    To resolve the issue, try one of the following options: 

    Option 1

    Install the Microsoft Access Database Engine 2010 driver from the Tableau Drivers website.
    Note: It may be necessary to uninstall drivers through the control panel before installing the correct version.

    Option 2

    Create a new Microsoft Excel or Microsoft Access file, and copy the data from the old file to the new file.

    Cause

    If Option 1 resolves the issue, the following are some possible causes:
    • Some features of Microsoft Office 2010 did not work with the Microsoft Access 2007 database driver
    • A Microsoft Access file contains macros.
    If Option 2 resolved the issue, the database file might have been corrupted.
