How can I convert a .ost from Outlook 2003 to a .pst file?

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.

  2. The easies way to open your .ost file on outlook is to export your mail account to a .pst file. You can open the file on other outlook applications.

  4. 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.

  5. I’m closing comments on this article because the majority have been thinly veiled product advertisements posted by various recovery and conversion utility producers. I have removed those. (Sorry if I removed legitmate posts from real people with real recommendations, but this was turning into an ad-fest.)
