Summary: You can convert an .ost from Outlook 2003 to a .pst by copying its contents into a new .pst file, but you must be able to open the .ost.
How can I convert an .ost from Outlook 2003 to a .pst file? I have tried ost2pst.exe, but it does not support 2003.

Well, to begin with, there is an (expensive) program called Exchange Recovery 2.0 that claims to handle the new 2003 file formats.

If you can open the OST file in off-line mode, you can then create a PST and simply copy the contents of the OST over to the PST. The trick here is opening the OST at all since it is typically tied to a specific profile or Exchange Server account settings. If that account is not available, then you may not be able to open the OST.
A Google Search for "OST PST conversion" returns several companies that provide for-fee conversion services.

I just recovered an Outlook 2003 .ost by converting it to .pst using the stellar phoenix demo program which was linked to above. Definitely helped me dodge an IT bullet.
