    Hi Anneke

    To better understand the issue, could you please provide a bit more information? 

    -What is the exact error message you receive when you click Open Outlook Data File? If possible, please share a screenshot of the error message. You can send the screenshot via private message to avoid exposing any personal or organizational information. 

    -What version and build of Classic Outlook are you using? (File > Office Account > About Outlook) 

    -Are you trying to open an existing.pst file, or does the error appear immediately after clicking Open Outlook Data File? 

    -Does the issue occur with all Outlook data files or only with a specific file? 

    Please understand that our initial reply may not always immediately resolve the issue. However, with your help and more detailed information, we can work together to find a solution.  

    I look forward to your update.
