How to Transfer Outlook Data to a New Computer?

Summary: Moving Outlook data files, such as .OST or . PST from one computer to another is quite easy and does not require much effort when you have access to your Outlook profile. The situation becomes complex when the Outlook profile is damaged or deleted/disabled from the Exchange Server. In such cases, the Outlook data file enters the orphaned stage and turns inaccessible. In this blog, we have explained the step-by-step procedure to convert and transfer Outlook data from an OST or PST file to a new computer. We have also mentioned an OST to PST converter tool to extract and transfer Outlook data, such as email, contacts, calendar, notes, tasks, etc., from an inaccessible or orphaned Outlook OST and PST data files to a new computer with ease.

How to Transfer Outlook Data to a New Computer?

There are many situations where you may want to move Outlook data, such as emails, contacts, attachments, notes, calendar items, tasks, etc., to another computer. For instance,

  • You have received or bought a new computer and want to move your Outlook data from your current system to this new computer running Microsoft Outlook.
  • You are using Outlook to access your Gmail or Exchange account and want to move the mailbox data from Gmail or Exchange mailbox to another Outlook, Exchange, or Office 365 account.
  • You want to move Outlook data from Outlook for Windows to Outlook for Mac.
  • To create Outlook data backups as there is no option to create automatic backups in Outlook.

You can export the mailbox items from Outlook using the Outlook Import Export wizard. All the mailbox data, such as emails, contacts, attachments, etc., are exported and saved on your computer in a .pst file format, which you can move or transfer to other computer and Import via Outlook Import Export wizard. PST files can also be imported into Office 365 and Microsoft Exchange Server.

However, if you can’t access the Outlook account or Outlook Import Export wizard due to a problem with Outlook profile or Outlook data file (OST or PST), you can’t export the mailbox items.

To transfer Outlook 2007, 2010, 2013, 2016, or 2019 data or emails from an inaccessible or orphaned Outlook OST file to a new computer, you need to convert the inaccessible offline Outlook data file to accessible PST file format.

Steps to Transfer Outlook Data to a New Computer

Let us understand the systematic approach to migrate and Import Offline OST file (OST/ PST) from one computer to another. For convenience and to make the process easier, we have divided the entire process to transfer Outlook data to another computer into four steps:

Step 1: Convert and export mailbox items from Outlook or Offline data file (OST)

Step 2: Transfer PST file to the new computer

Step 3: Create a new Outlook profile on a new computer

Step 4: Import the converted PST into the Outlook profile on the new computer

By following these steps, you can

  • Transfer Outlook 2007, 2010, 2013, 2016, or 2019 data to a new computer.
  • Transfer Outlook data and settings to your new computer.
  • Transfer Outlook calendar items, attachments, contacts, etc., to another computer.
  • Move mail items from Outlook 365 to a new computer.
  • Move personal folders from one Outlook to another.

NOTE1: Folder properties, Outlook settings, etc., are not preserved while exporting the data. Only the mailbox content is saved to the exported PST file.

NOTE2: You can’t access or use Outlook’s Import and Export Wizard if the Outlook profile is disconnected from the server, damaged, or belongs to a disabled/deleted mailbox. In such cases, the Outlook data file becomes inaccessible. However, you can use an OST to PST converter software, such as Stellar Converter for OST, to convert inaccessible and orphaned Outlook OST or PST files to a new PST file. You may also export the converted mailbox items from inaccessible Outlook data files directly to an existing Outlook profile, Office 365, or live Exchange account. The software also helps convert encrypted Outlook offline data files (.ost) into PST.
