The major disadvantage of using the ScanPST is you need to run it multiple times to repair PST files. And also it cannot repair the severely corrupted Outlook PST file. During such instances, you can make use of the Remo Repair PST tool.

Why Use the Recover Lost and Found folder?

Once the ScanPST repairs minor Outlook PST file corruption, open your Microsoft Outlook account (If you use multiple profiles, then open Outlook with the repaired PST file). And follow the steps to access missing or deleted emails, contacts, reminders, and other Outlook folders.

In Folder List, locate the Recovered Personal Folders, a folder that gets created after repairing the PST file. And it contains all your default folders like Calendar, Contacts, Deleted Items, Inbox, Journal, Notes, Outbox, Sent Items, and Tasks.

If you find the above recovered personal folders empty, then look for the Lost and Found folder. It contains all the recovered items. However, the recovered Outlook items cannot be placed in their original structure. To overcome this issue, you can create a new Outlook PST file.

Steps to create a new PST file:

  • Open Outlook and go to File > Info.
  • Click on Account Settings and then, Account Settings.
repair Outlook pst file
  • Select the Data Files and click on Add tab.
replace outlook pst file with repaired pst file
  • In the File Name field, enter the PST file name of your choice.

  • Click OK. This will create a new PST file.

Note: Creating a new PST file, will help you import the recovered items from the Lost and Found folder to your desired path. In your new Outlook PST file, you can just drag the recovered Outlook items from Lost and Found or Recovered Personal Folders to your specified location. And later, you can delete the Lost and Found/ Recovered Personal Folders.

Recover Additional Outlook items from Repaired PST file using .bak file:

A .bak file is a backup file created by the SCANPST tool during the PST file repairing process with the same name as the corrupt .pst file under the same location or folder but with a .bak extension. With the help of this backup file, you can recover the extra Outlook items that cannot be restored even after using the inbox repair tool.

Steps to Recover Additional Outlook items using .bak file:

Go to the PST file location or folder > locate .bak file > Make a copy of the .bak file > Rename the .bak file extension to .pst file (for example outlook.bak to Outlook.pst) > Import the .pst file in your Outlook using Import/Export wizard.
