Converting OST to PST...

try running StorStat utility from your Outlook or Office CD on your ost file and see what it gives you.
but for the most part unless you have the outlook profile you used to create it and have not changed it you are SOL.
Offline Folder files (OSTs) are considered slave replicas of the server- based
folders. If you delete the master, the slave is orphaned.
If the original Microsoft Exchange profile was not modified, you can still start
the Microsoft Exchange client offline with the old OST and recover the data by
moving the messages from the OST to a PST file. However, if the old profile was
deleted or modified (by using it to log onto a different mailbox) then the data
in the OST is lost.
MORE INFORMATION
================
You can recover mail stored in an OST, provided that you have not tried to
modify the profile that was used to create the OST file. If the profile used to
create the OST file has been modified to point to a new mailbox, the information
contained in the OST file may be lost.
This is because security on an OST works so that Windows NT authentication cannot
be used when you work offline. Therefore, you must "prove" that you're allowed
to log onto the server-based master before the OST file gives you local access.
To do this, Exchange Server creates an encrypted "cookie" from your mailbox's
unique entry ID while you are successfully logged into the Exchange Server
computer. This cookie is securely stored in your Exchange Server profile.
Essentially, your profile stores this key for the OST. Every time you try to
access the OST file it checks your profile for the existence of this key.
If you modify the profile or try to connect to a new mailbox or new server with
the current profile, Microsoft Exchange replaces this key with a new value from
the mailbox that was created. At this point, you cannot access the data that was
contained in the OST created against the first mailbox.
