When the users first set up their email account in the MS Outlook application, the application downloads all the data from the mailbox & stores everything in an offline file known as OST or Offline Storage Table file. If due to some known or unknown reasons, this OST file gets corrupted, then you will not be able to access your profile. The perfect way to avoid this situation is to keep a proper & a regular backup. The OST file is not directly accessible by the Outlook application, so you need to convert it first to a PST file & then repair it to get back all the data. Therefore, you need a software to convert .ost into .pst file.

First try this approach –

  1. Launch the MS Outlook application & log in to your account.
  2. From the menu select “File” – “Import and Export”
  3. Choose “Export to a file” from the actions list & hit the “Next” button.
  4. Select “Personal Folder File (.pst)” as file type & then click on “Next” button.
  5. Check the checkbox next to “Include Subfolders” & click on “Next”.
  6. Browse to the destination location to save the newly created PST file & then hit the “OK” button.
  7. Click “Finish” to start the converting of OST file to PST.
