I am an Outlook user and I was completely stuck when I had to work on the older version of PST file and then I had to compromise on my output. Then, one of my friends advised me this reliable PST upgrade software. The best part of this tool is that it can perform both upgrade and downgrade processes in a single shot. Great product!!
