Kernel for OST to PST has amazing set of options at every stage of operation, I must say options for doing everything. For searching OST files, for saving data, for filtering, and for analyzing the file content. And the tool is not that difficult to use too.

I purchased this tool many years back and I was a little surprised to see that its license was for lifetime, and I could upgrade to the latest version without any additional payment. The updated version has many new features added to it.
