What should I do after fixing PST file using ScanPST file?

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:

  • In the File Name field, enter the PST file name of your choice.
  • Click OK. This will create a new PST file.

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.
