How to add .ost, pst. files as data files for MS outlook 2007 exchange with hosted 3rd party

I have several of the .ost and .pst data files that I am trying to make as mailboxes (with the inbox and other subs that I created) but when I try it says they are not personal folders. I had changed one pst to ost and it worked but not the others. I thought .pst was the right suffix for these types of files?

Secondly can I merge or do something to combine these different files?

I am using Microsoft OL 2007 with hosting from MyHosting.com and it is on my laptop using Windows Ultimate 64 bit as my operating system. If it matters I have a Toshiba Satellite C655d-S5043.

I also have Exchange and Enterprise via my Blackberry to sync with outlook through myhosting., com which is much more satisfactory than Go Daddy which I had nothing but problems with (maybe because I am too stupid to know how to follow rules)

You can NOT take an .ost file from a machine and import it anywhere without 3rd party tools.
A .OST file is just a local cache of data that is held in an exchange server account. It is not meant to be used as a means of import/export.

Why can I not make it a data file for my outlook like the others that are there. I will attach a snapshot of what I am looking at.

I could not see any OST file in the attachment.

furthermore
you cannot attach OST file to outlook.

You will have to export the mailbox to PST to attach.
or
you have to convert OST to PST to attach

Can you point me to how I can go about doing that or is that the basis of the link above (the response just above yours)?
