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.
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 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.
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
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. To know the step-by-step process for converting OST file to PST using the software, read How to Convert OST File into Outlook PST file?
Considering your Outlook account is active and in sync with the mailbox server and local Outlook data file (OST or PST), you can export the mailbox items and take a backup of Outlook emails, contacts, calendar, notes, tasks, settings, etc., to PST file using Outlook’s in-built Import and Export wizard.
The steps to export mail items to PST via Outlook Import Export Wizard are as follows:
Note: You can also connect a USB media or external hard drive to the computer and select it as a save location for the PST file. This helps move the file to a new computer.
This will export and save all the emails and other mailbox data, including attachments, from the Outlook data file to a portable PST file.
Important Note: The Import Export wizard exports the Outlook data from the local cache (OST or PST). Thus, it exports the mail items stored in the local Outlook data file, which contains data from the past 12 months. To export all data, disable Cached Exchange Mode in Outlook.
After converting the Outlook mailbox data from the OST file to the PST file, transfer the converted Outlook PST data file to a new computer. To do so, copy the converted PST file to any external storage media, connect this storage media to a new computer, and then copy the PST file on the computer’s hard drive.
However, if you could not export Outlook data via Import Export wizard, follow these steps to locate and convert the original Outlook data file using Stellar Converter for OST software.
Note: By default, the Outlook data file is stored in C:\Users\YourUserName\AppData\Local\Microsoft\Outlook\ folder. However, the location may vary based on the Outlook and Windows version and edition. For more details, refer to our guide to Locate the OST file .
Note: The free demo version allows you to preview unlimited mail items and save up to 20 items per folder. To save all mail items, activate the software using a valid activation key.
Copy this converted PST file to your new computer where you want to transfer the Outlook data.
Skip this step if you want to import the PST file into an existing Outlook profile on a new computer. However, you may create a new Outlook profile on your computer to import or access the converted PST file.
