How to Export Contacts from OST File to PST
Now that the reasons for exporting contacts from the OST file to PST are clear, let’s move forward to see the methods available for exporting contacts to PST.
1. Export Contacts by using Outlook’s Import/Export Wizard
You might be aware of the Outlook’s Export and Import functionality, which allows to export mailbox data to PST file. You can also use this functionality to export your contacts to the PST file. Here’s how you can do this:
- Login to Outlook with the associated profile.
- Click on the File tab in the top-left corner.
- Click on the Open & Export option in the left pane and select the Import/Export option.

- On the window that appears, select the “Export to a file” option. Then, hit the Next button to continue.

- Select the Outlook data file (.pst) in the Export to a File window and click Next.

- You’ll now see all your mailbox folders listed. Scroll down and select the Contacts folder, and click on Next.

- Then, choose the location where you want to save your PST file by clicking on Browse, and then click on Finish.
- Once you click on Finish, Outlook may ask you to set a password for the PST file.
- This option is optional. If you want to protect your PST file, set a password, and click on OK. Else, click on OK without entering the password.

Outlook will save your contacts in the PST file at the given location.
Note: This method only works when your Outlook profile and the associated OST file is accessible.
2. Export Contacts through the Drag & Drop Method
If you want to export a few specific contacts rather than the entire folder, then there is a workaround you can use. In this, you have to first create a new PST file and then drag and drop the contacts, you want to export, into this file. Here’s how:
- In your Outlook, create a new PST file. For this, click on New Items under the Home menu and click on More Items.

- Select the Outlook Data File… option from the dropdown.
- Give a name to the PST file, for example, MyContacts and select a location/folder to save it.

- Select the contacts that you save in the PST.

- Drag and drop them into the new PST (MyContacts).
