Assess the Problem

This error “The data file ‘Personal Folders’ was not closed properly. The file is being checked for problems” appears when MS Outlook is opened in Outlook 2007.

Data File Personal Folders was not Closed Properly

The first step is to analyze the cause of the problem. Here, Outlook is taking too long to respond then the first thing that strikes is the size of Outlook data file.  Over the time, the size of Outlook PST file becomes too large. As a consequence users face difficulty in opening and accessing the Outlook.  This can be an issue of corruption in PST Files and unless the corruption issue is resolved, the problem is not resolved.

Resolve the Error

  1. Reduce the size of PST File: Most probably the error is related to the oversized Personal Storage Tables or PST File. In that case, reduce the size of PST file and resolve the error. The process involves archiving and compacting:
  • Start Outlook and go to File tab. Click on Info
  • Click on Cleanup Tools. Next click on Archive
  • In the Archive Dialog box, perform the following steps:
  1. Enable Archive this folder and subfolders option
  2. From the list of Folders, select the PST file to be archived
  3. From the drop-down list with the name Archive Items Older than, specify a particular Date for items to be archived.
  4. Select Destination path and archive into a new PST file as you maybe archiving a large number of email messages.
  • Compact PST and save at a preferred location
  1. Repair PST using ScanPST.exe file: If archiving and compacting PST does not fix the problem then try to repair the PST with scanpst.exe.
  • Exit Outlook application and start Scanpst.exe manually. Location of Outlook repair tool varies with Outlook versions and different Windows. Know your Outlook and Windows version and locate the Inbox repair tool.

  • Browse the PST to be repaired. It should have an extension .pst
  • Click on Options and provide the Scan Log option
  • Click on the Start button. If there are errors detected during scanning, the exe-file prompts to start the repair process
  • During the process, a backup file is created to avoid data loss. Save the backup file at a preferred location.
  • Click on Repair button and start Outlook using the profile with PST file
  • In the list of MS Outlook, locate the recovered Personal Folders with default Outlook folders or Lost & Found Folder. The recovered folders are mostly empty due to the fact that it is a rebuilt PST file, whereas the Lost and Found folder contains items as retrieved by Scanpst.exe.
