How to Read OST files from outlook without a tool ?

Hi Experts,

I have an old OST file (6GB!)  created via outlook 2003 which i want to read on outlook 2003 or 2007, Can this be done solely through outlook without the need of any specialized tool that should convert OST to PST first ? and if tool is needed, is there any open source or free tools to do so ?

You cannot directly read an .OST file with Outlook unless you first convert it to a .PST file, or you have a previously configured profile that used the .OST, where you can disconnect your network cable, open up Outlook and that should show you the contents of the .OST file, at which point, you can export the mailbox to a .PST file and use that.

If you can access the Exchange mailbox for the .OST, you may also backup and then remove the old .OST file, then resynchonize the mailbox and get a new .OST file with the messages and other items. Then you can export or even just create a new PST file and then copy all the contents in your OST file to the PST file.

A third party tool is needed to accomplish the task.
