While cleaning up the duplicate files from a folder, the user mistakenly deletes the contact folder. But the OST file maintains a local copy of the mailbox data. Hence, we can extract contacts from OST file before the next synchronization. In this article, we will share multiple techniques for extracting contacts from an OST file. Moreover, to avoid errors during the process, use the Cigati OST to PST Converter. It simplifies the process without any risk of data corruption.

Importance of Exporting Contacts from OST File

Many organizations extract contacts from Outlook OST file for legal compliance and audit purposes. Below, we have listed several practical reasons for this extraction process:

  • If the Outlook fails to load, retrieving contacts from an OST file is the only solution.
  • When upgrading to a new system, users back up contacts from the OST to transfer them when needed.
  • The user can still extract contacts from the OST if the company deactivates their email account.
  • In the event of file corruption or data loss, it is advisable to export the contacts from the OST file separately.
  • You can retrieve contacts from the OST cached file in case a contact folder is mistakenly deleted. 

Simple Ways to Extract Contacts from OST File 

You can retrieve the contacts from an OST file using a manual method using Outlook. Moreover, a professional tool is also introduced that makes the process simpler and effective.

#1: Manually Export Contacts from OST File

To successfully execute this method, make sure to link your OST file with the Outlook profile. It exports the OST file data in a PST file, and then this PST file can be imported into Outlook.  

Use the following instructions to start the process:

  1. Open MS Outlook and head to the File tab.
  2. Then, press Open & Export > Import/Export and select Export to a file.
  3. Click Next and then choose Outlook Data File (.pst) > Next.
  4. Now, press on the Contacts folder and choose a destination location, and save the resultant file. 
  5. Finally, hit Finish.

#2: Extract Outlook OST Contacts File by Archiving

Users can back up older contacts from the OST file by using Outlook’s Archive option. This is the best option to extract older contacts from OST rather than deleting them.

The following are the steps to initiate the process:

  1. In the Microsoft Outlook application, press the File tab.
  2. After that, go to Options > Advanced.
  3. Under the AutoArchive section, click on AutoArchive Settings.
  4. Now, choose Archive this folder and all subfolders.
  5. Then, select the Contacts folder that you would want to archive.
  6. Browse and choose the path to save the resultant archived PST file, and click Ok.

Challenges Faced by the Users with the Manual Methods

  • If your OST file is orphaned, the manual procedure will not work.
  • It will take a considerable amount of time while handling a large list of contacts.
  • The Archive method will not archive the recent contacts. It will only archive the older contacts or the older contact list.
  • The user has limited control over the archiving process.
