  • Hi parikia,

    Microsoft Outlook doesn’t support manually opening or importing items from an offline Outlook Data File (.ost).

    More information, please check Open or import items from an offline Outlook Data File (.ost)

    Further, Outlook uses OST files for Exchange accounts or Hotmail/Live/MSN (MAPI) accounts. The data in the OST file is a mirror image of what is available on the email server, and you should ideally be able to retrieve this data from the server when you re-configure the account in Outlook.   

    If this is a Hotmail/Live/MSN account, we may recreate the account profile and then using Exchange Active Sync (EAS). Follow the steps in the thread below: Set up Hotmail with Outlook 2013 Preview,

    If this is an Exchange account, please consider seek help at the Outlook forum:

    https://social.technet.microsoft.com/Forums/office/en-US/home?forum=outlook

    Hope the information above is helpful.

    Best regards

  • If you want to convert OST file to PST format, you can use few easy manual tricks that require no 3rd party tool. Microsoft Outlook client has few built-in features which you can use here, such as Archive, Export, Move, and Drag & Drop. By using these features, you can successfully import mailbox content from OST to PST file. 

    But before you can use any of the manual tricks shared in the above article, make sure: 
    1. You're using the same computer system on which the OST files were originally created.
    2. You're connected to the Microsoft Exchange Server.
    3. And most importantly, the OST files are not corrupt.

    If Manual method is not working then you can go with any third party tool like - https://www.datavare.com/software/ost-to-pst-converter-expert.html

  • Hello, I agreed with Michael Shao. As we know that Microsoft Outlook applications don't provide the option to import the OST file in MS Outlook application. So you first have to convert OST to PST and after that, by Importing the PST file data in Outlook application you can access data items. I hope this will help!
