Thanks for your replies.
From what I have read on the OST, an encrypted cookie is stored in the OST
which helps the profile match up with the OST to enable outlook to open it.
If we know the data structure(?), then possibly we can use a hex editor to
replace that area of the ost with the values from the new ost? Just a
thought or am I barking up the wrong tree?
Is it possible to reset the registry entries to enable the OST recovery?
Kernel for OST to PST conversion is the user-friendly easy to use recovery tool. The tool can recover orphan, corrupt or lost OST files and save them in PST, EML, DBX or MSG format quickly. The tool is meant for everyone, that is, thanks to its interactive screens and easy GUI even a novice computer user can recover his OST files. The tool effectively recovers permanently deleted emails as well. To know more about tool visit http://www.convertosttopst.co.uk/
