How to Transfer Outlook Data to a New Computer

Summary: Transferring Outlook data (OST) manually from one computer to another computer is a complex and tedious process. In this blog, we have explained the step-by-step procedure on ‘how to transfer Outlook data to a new computer’ that can help you to perform this complex task with ease. In addition, you’ll find an automated tool that can easily convert OST file (even orphaned or inaccessible) to PST in a few simple steps.

You may come across situations when you’re required to transfer Outlook data to a new computer. However, transferring Outlook data to another computer is not as simple as it seems. You can transfer Outlook to new computer without much difficulty, if you’re using the application with POP account as it creates PST, which is an Outlook importable file format. For such accounts, you just need to extract the PST file, move it to a new system and import it into the Outlook account.

However, like PST, you can’t just copy and move the Outlook OST file, which is created when you configure your Outlook with Exchange or IMAP account. Outlook OST file can only be accessed with the same account (from which it is created) and on the computer that is used to create that Outlook account. So if you want to migrate Outlook OST data to new computer, you need to first convert it to PST file format.

TIP: Outlook Import and Export wizard cannot convert orphaned or inaccessible OST file to PST. We recommend Stellar Converter for OST software to perform OST to PST file conversion in a quick and error-free manner. The software can also help export encrypted Outlook offline data file (.ost) to PST.

To get started, you first need to export the OST file to PST so that you can easily import it into the Outlook account on a new computer. The process is made easier when divided into the following:

  • Export & Move Outlook OST File
  • Import the converted PST into Outlook on another machine

Let’s understand the step-by-step procedure to export, transfer, and import Outlook data from one computer to another.

Step #1: Export & Move Outlook OST File

Considering that your Outlook account is working properly and the OST file is accessible, you can export the OST file to PST by using the Outlook’s in-built Import and Export wizard.  

Follow the steps below:

  • Open and log in to MS Outlook.
  • Go to File> Open & Export> Import/Export.
  • From the Import and Export Wizard window, select Export to a file and then click Next.
  • When Export to a file window opens, select Outlook Data File (.pst) and click Next.
  • Select the mailbox folders and mailbox items that you want to export. Also, check the ‘Include subfolders’ checkbox and then click Next.
  • Click on the ‘Browse’ button, select a location to save the PST file.

Note: You can also connect a USB or external hard drive to the computer and select it as a save location for the PST file. This helps in moving the file to a new computer.

  • Once the process is completed, click ‘Finish’. When a password prompt pops up, click ‘OK’ without entering the password.

This will save all the emails and other mailbox data from Outlook OST file to the PST file, which you can easily import into any Outlook account, on another computer.

Important: You can’t use the Outlook’s Import and Export Wizard, if the OST file is orphaned/inaccessible or the Outlook account is inactive/not working. However, you can easily convert such inaccessible OST files to PST by using the Stellar Converter for OST software.

After converting the PST file on the existing Windows machine, move this Outlook PST file to another computer. To do so, you need to transfer the PST file to any external storage media. Now, connect this storage media to another computer and copy the PST file on the computer’s hard drive.

Step #2: Import the Converted PST File into Outlook

After moving the PST file (converted from OST) on a new computer via an external storage device, you need to import this PST into Outlook. First of all, ensure that MS Outlook is installed on the machine. Now, follow the given steps to import PST to Outlook.
