There aren't, sadly. In order to do that type of file conversion, software developers must first pay licensing fees to MS, which precludes any kind of free solution.

Hi Smith,

You can try Outlook to convert OST to PST. You need to have Outlook in Offline mode, import the OST. Start a backup of Outlook. You should have the PST files

You have this tool too:

As was said, there is no free version that will fully do it, just free demos. Then again, why do you need to do this? Maybe there is a better way to accomplish what you want. Using PST is not a good idea unless you have to. See here:

Hi,Smith

Here are some ways you can try to convert OST to PST.

1.  You can copy all the contents in the ost file to the pst file in Outlook manually. But for that, you need make sure that you can open the ost file to get all the contents. And you can also just export the content in ost file to pst file in outlook. More details at

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


2.   If you can access the Exchange server with the the OST file, you can use Export-Mailbox command to export the data into a PST file. Below is the detalis:

3. Or maybe you can try to use VBA code to do the conversion automatically. Here is an articel about this. Hope it helps.

There's no freeware tool that can convert OST to PST format. But if you're looking for a free solution, you can try some easy manual tricks. This article contains some useful information about how to import mailbox content from OST to PST format manually - semnaitik.com/convert-ost-to-pst/

Since there's no way to convert OST to PST format at free of cost, you should try to import the mailbox content from OST to PST file by using the built-in features of MS Outlook, such as Archive, Export to a new PST file, Move the items to a new PST file, Drag & Drop. You can find the complete information in the above article.

Thanks.
