As you know that an offline ost file does not open by default in MS Outlook. You can export OST file into PST file format after that you can access all OST file data as PST file in MS Outlook mailbox using third party OST to PST Converter.

In addition to this, I would like to suggest a one more alternative i.e. SysInfoTools OST to PST Converter. This Software is helpful in doing the OST to PST file conversion. It easily repair your corrupt Exchange OST files and convert them into PST, EML, MSG, MBOX or Archive mailbox. You can get it freely from here:
