an OST is only a local copy of your exchange mailbox
if you are trying to take that mailbox and import to an account on 2016, just export the 2013 mailbox to PST then import on 2016



stellarservertools can be used for this purpose.

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 to PST conversion.

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


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:
