Table of Content

    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 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 Hosted Server account or 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.

    Step 1: Export Outlook Mailbox Mails and Other Items to PST

    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:

    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.

    Step 2: Copy Outlook Data File to New Computer

    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.

    Unlike PST, there is no direct way to transfer Outlook OST or cache Exchange mailbox data to a new computer. Instead, you need to first convert the OST to PST using the Outlook Import and Export wizard or a third-party OST converter tool, such as Stellar Converter for OST. The software can also convert orphaned or inaccessible Offline Outlook data file (.ost or .pst) files to new PST. This professional converter tool can export encrypted Offline OST files to PST in an error-free manner. Once the offline OSt file is converted to PST, you can quickly transfer Outlook data to a new computer and import the PST file into any Outlook account or profile.

    1. I had to copy the OST file manually(outlook 2010) user could not log in to the domain. I copied file by copy and paste on a flash drive while logging as admin of the old pc. On new pc which is windows 10 and outlook version is 2019. While setting up it ran into issues. I finally created a profile and pointed to the outlook files folder which I created under documents. I see the size of the file as 15GB but in outlook, only 21,000 items are appearing.

      Most of the old emails have not downloaded.

      I did not use any softare to create ost file. Please advise.

      Thanks, B

    2. Hi,

      Thanks for your information.

      I’m most of the time using Outlook on my PC. However, there are situations where I’m traveling for an extended period. What I have done so far with Outlook 2013, is just copied the .pst file from my PC to the Laptop and coming back home, copied the Laptop .pst file back onto the PC. This so far was an easy and straight forward way in keeping up with my mail.

      As far as I can see, this procedure always worked without a problem. So I’m wondering if I miss something? Might my way of doing copy/paste for the .pst file be a problem for office 2019?

      Thank you so much for your reply.


      1. Hi,

        Please do any manual operations carefully to avoid any bad outcome in Outlook. Please follow the steps as mentioned the above.

        You can also contact our support team for a better understanding.

    3. Hi,

      Thank’s for the insight. Finally, I get a clearer view about moving Outlook, and their related NST, OST, and PST.

      Back in POP3 times, it sounded easier somehow to migrate mailboxes within an organization.

      I still have a question!

      My organizational outlook clients all use exchange by now, plus a few O365 accounts and some legacy users still at POP3.

      But I’m going through a major hardware upgrade.

      As I see, if everybody is using exchange, I don’t need to worry about backing up OST and NST, because my new client will sync everything from the online exch server.

      Am I right?

      Again ty for the article.

      1. But, you should also take backup of offline folders to avoid last minute rush during Exchange Shutdown or bulk migration.
