When publishing a workbook with a live connection to a Microsoft Access file, the following error might occur:
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.



  • Tableau Server
  • Microsoft Access or Microsoft Excel file


  1. Uninstall any currently installed versions of the Access Database Engine driver.
  2. Reinstall the 2010 x64 version of the access driver, more information can be found on the Driver Download page
  3. Try to publish the workbook again.


The error may be due to the following causes:
  • Tableau Server is using the 2007 version of the Access driver with a macro enabled access database.
  • The same file is being used between multiple users on a shared network.
  • The Access driver version is corrupted.
