Thanks. We'll let you know when a new response is added.

Outlook does not allow opening of OST file outside of its MAPI profile. However, if you have the outlook profile (must be connect with Exchange Server) that created the OST file. Then simply recreate a new ost file and it will be automatically synchroniszed with Exchange Server mailbox data. And you can automatically download the data of Exchange Server’s mailbox. 

See here how to open OST file of Microsoft Outlook;

    There is no manual method for importing the OST file to Outlook.

    However, if you have the outlook prolife that created the OST file. Then simply recreate a new ost file. The OST file will be automatically synchronized with the exchange server and data will be downloaded back from the server to the ost.

    For more info check the link:

    If the original MAPI profile that created the ost file has been deleted and you are left with only the ost file.
    Then you will not be able to import and access the ost file directly into outlook. To access its contents, first you need to convert it to PST format then import the converted PST file into outlook.

    There is no manual way or an inbuilt utility provided by Microsoft outlook to open or import OST file in PST format. So you have to go for a third party utility like MS Outlook OST to PST Converter as they help in converting OST file in PST format. If you don’t want to spend money on the full version of the software then use demo version as it helps in converting a particular number of items in Outlook PST file format.

    Hi,

    Try Open File Tool, which is all-in-one software.
    - Open .ost files of Microsoft Outlook + Microsoft Exchange; 
    - Open .pst files of Microsoft Outlook 
    - Convert ost to pst files 
    - Repair .ost files of Microsoft Outlook + Microsoft Exchange; 
    - Repair .pst files of Microsoft Outlook + Microsoft Exchange; 
    First two are available in DEMO version of OST Open File Tool for all. or try some recovery software.
    Check the resource Outlook 2010 Problem 

    Hope this helps.

    If you can't open your Personal Folders file (.pst) or your Offline Folder file (.ost), or you suspect that your .pst or .ost data file is corrupted, you can use the Inbox Repair tool (Scanpst.exe) to diagnose and repair errors in the file. The Inbox Repair tool scans only the .pst or .ost file, not your mailbox on the server running Microsoft Exchange. The tool determines whether the file structure is intact. If it is not intact, the Inbox Repair tool resets your file structure and rebuilds the headers.

    You cannot directly open or import OST file in MS Outlook, to open OST file and view its data you first need to convert OST file to PST file format then you can import converted PST file in your MS Outlook. See here to know how to convert OST file to PST format.

    We see questions about this file type all the time. What are people trying to get out of an OST file type? Are they just curious? There is no easy way to file this file type. It needs to be converted before any usable info can be derived from it. A simple Google search results in over 500k pages on this..
