Orphaned Outlook ost file

I recently had a user rename there ost file to ost.old.  They then delete there outlook profile and created a new profile.

Is there any way to recover data from the orphaned ost file without using software I need to purchase?

An ost should have re-sync'd from the exchange server unless for some reason you had disabled the cache mode setting.  what data was not brought over to the new profile? Are you looking for the autocomplete data?? Then what version of Outlook?

This is a tough one. I am sorry this happened to you as it has happened to me. I know there are tools out there to recover the .ost file but have not used them.

What happened to me was I switched out domain controllers. What I had to is reconnet the person back to the old server, get the mail out of the .ost file and create a .pst file, transfer mail, then unjoin them from the old domain and rejoin them to the new domain. The GUID file is what you seek.

Sorry, I have left out some important information.

The Exchange 2003 DB became corrupted and a new DB was created so there was no syncing from the server to a new ost file.

For most users I was able to export there original ost, whil outlook was in recovery mode, to a pst, create a new profile in outlook and inport the pst file.

To recover .ost files you probably have to use the cheater method by naming the file back to what it was.  Create a new profile and connect it, close outlook, drop the .ost back in, and hope it opens.  Otherwise you would be looking at a 3rd party to extract the data from the .ost file.
You can try the scanost tool on the file to see if you can repair it enough to export it like you did to the other users. Outlook 2003 should have it under the common files folder. Outlook 2010 will be in the Office14 folder, and I think you run the scanpst and select the ost.

Thanks to all of you for your input.

I have purchased an ost to pst conversion software and it is working well.
