How to import an OST file into MS Outlook?

Import OST file into Outlook

OST file or Offline storage table enables exchange user to use their mailboxes in offline mode. It synchronizes with MS Exchange Server after internet link is re-established on the server. However, OST synchronization with Exchange Server fails due to the following reasons:

  • Disruption in internet connectivity
  • Crash of the Exchange Server
  • System shutdown due to power failure
  • Improper shutdown of MS Windows
  • Corrupt hard disk

Possible outcomes of the OST corruption

OST file holds a single user mailbox in the cached Exchange mode. It enables user to send or receive emails when MS Outlook is disconnected from the Exchange Server. However, OST files are also not free from corruption issues. Corrupt OST file displays various error messages, some of which are shown below:

Cannot open your default email folders. The file xxxx.OST is not an offline folder file
Errors in Background Synchronization
Errors have been detected in the File Outlook.OST

Corruption of Exchange OST files will generate following possible outcomes:

  • Some folders of an Exchange mailbox may become inaccessible
  • Some or all user mailboxes on Exchange Server may get damaged
  • Changes stored in the OST file will not appear in the Exchange mailbox

Importing OST file into Outlook

You cannot access emails, attachments or other data of the OST file when MS Outlook is not connected with the Exchange Server. However you can import OST file into Outlook PST File format by using the following steps:

1.Open your Outlook profile
2.Connect to the Exchange Server to access emails of your Exchange mailbox or OST file
3.Now go to File>Import and Export
4.Choose “Export to a file” option from the list and click Next
5.Select “Personal Folder File (.PST)” and press Next
6.Tick the “Include Sub Folders” check box if you want to export entire data of your Exchange mailbox
7.Press Next and click “Browse” button to select destination folder for the exported OST data

However, manual OST to PST conversion option works only when OST file is working or not severely damaged and you’re able to access your mailbox on the Exchange Server. Therefore, the best option to deal with severe OST corruption issues is the usage of third party software.
