Working with Outlook in Offline mode generates an Offline Storage Table i.e. OST file. Any changes made to your OST file in offline mode gets automatically synchronized when network connection re-establishes. Thus, your OST file is a replica of entire attributes stored on the Mail Server. So, it is not required to back up your OST data. Hence, most of us don’t do it also.

On the other side, you might be having a lot of contacts stored in your OST file, as you are using it for a long time. You may happen to delete important contacts accidentally or they might go missing due to some unknown reasons.

So, how to recover your contacts from OST file? Well, in this article, I am going to explain two different techniques to retrieve your contacts from OST file.

Technique 1: Traditional Way to Recover Contacts from OST File

  2. Select the contacts that you want to recover.
  3. Next, right-click on your selected contacts
  4. Choose Move option from the background menu
  5. Opt Other folder option.
  6. In emerged Move Items wizard, specify the folder to save your recovered contacts.
  7. Select Contacts and hit the OK button.

This trick can be used only to recover temporarily deleted OST contacts. In case, you have emptied Trash folder after deleting contacts from your OST file or you want to restore lost contacts then try the next method.
