Outlook is the most robust and reliable email communication manager. However, just like any other program, Outlook is also vulnerable to corruption and errors. One such common error received is, “Unable to display the folder.” This error mostly occurs due to PST file corruption issues or some hardware issues with the system.

Below are a few tips that you can keep in mind while working with PST files.

  • Do not overload PST files
    The latest Outlook versions allow PST file size limit up to 50 GB. But if the files become large, Outlook can encounter some errors.
  • Do not store PST files on Server or Network Drive
    Avoid storing PST files on your Server or any network environment. PST files are to be stored in the local drive to avoid any corruption or damage.
  • Avoid sudden system shutdowns
    While working on Outlook, avoid any sudden system shutdowns. Make sure to exit Outlook before shutting down the system. Unexpected system shutdowns can damage the PST file to a larger extent.
