The ost file is just a local copy of the mailbox on the server. If a trojan ate it, the mailbox will resync. If it deleted the mail, then you'll need a backup file - if you have a good copy of the ost, you may be able to restore it to Outlook (if it was created using the same profile) and export to a pst. Do this while outlook is working offline. Go online and import the pst to the mailbox to restore mail.

If outlook won't accept the backup ost, you'll need to use an ost to pst utility. I have a list here: Convert an Offline File (.ost) to a Personal File (.pst)
