Why not just export the ost to a pst from Outlook?

The problem is that all that I have is the OST file I don't have the computer with the user’s Outlook profile.

So then you need to use the tools we suggested. The format is proprietary so the vendors have to research the methods to convert.

Buy your own license and then you can convert files for others.

Hi,Knowledgeable

There are several methods to convert OST file to PST file.

First, Microsoft does not provide an official tool to do the conversion. However, if you can access the contents of the OST file in your Outlook, then you can perform the conversion manually, as follows:


1. Start Outlook. Make sure you can access all the contents in the OST file to be converted.
2. Create a new PST file.
3. Go to the OST file, select and copy all the contents to be converted with your mouse.
4. Go back to the new PST file, then paste all the contents into the PST file


That will do the ost 2 pst conversion.


You can also perform the conversion by exporting the contents of OST file to PST file by following the instructions at:


http://office.microsoft.com/en-001/outlook-help/export-outlook-items-to-an-outlook-data-file-pst-HA102534110.aspx


Second, if you can access the Exchange server containing the account data for the OST file, then you can use Export-Mailbox command to export the data into a PST file, similar to convert your OST file into a PST file. Below is the article about doing that:

Third, you can try  a free OST to PST converter via Outlook VBA . Below is the article about doing that:

It is possible to convert ost file for free, if you still have the account where the .ost file was created from. For this, you just need to create a new .pst file and then manually move the items from the .ost file to pst file.

There are some 3rd party tools that can convert ost to pst. As Mr Hurst suggested, you can use Stellar OST to PST Converter software. The software easily exports ost file to pst format. You can check the demo version from this link: https://www.stellarinfo.com/convert-ost-to-pst.php
Hello
As far as i know there is no free OST To PST Converter Tool.  

ARCHIVING FILES

You can use Archive to move or copy data to a PST file - this method works well when you have to move almost everything in your mailbox.
Note - you cannot archive Contacts

EXPORT OST INTO PST FILE

"Import and Export" is MS Outlook’s inbuilt feature used for converting mailbox data from one client to another. By the help of this feature, you can swiftly convert Exchange Server’s OST file to PST. It also allows conversion of OST to CSV and Excel format.

MOVE FILE ITEMS TO A NEW PST

Through this method, you can create a new PST file and drag the folders you want to move to the PST.
Dragging default folders such as  Inbox, Contacts, and calendar, is not possible.  A message will be displayed that you can't move default folders.

FORWARD BY EMAIL

If you don't have too many files for converting, then you can email them to your personal email address. Just select the items, then right click and choose Forward. If you have many OST files, you could drag the files to a new folder in My Documents, then just zip the folder and email that zip file.

or else you can try at try out this tool from cnet

As already mentioned by many experts, there are various conversion tools available and as far as i think none of them are free.
Manual options wont work in your case as you don't have the system in which the OST file was originally created.,

But if you only need to view the data stored in the OST file, these are some tools that let you preview data using their demo versions. These tools wont let you save the data but will definitely let you preview the data (if that is all you need) stored in that file.
