Even if you are satisfied with the product and how does it perform you still want services to be that good and I am glad they have not forgotten this. Once you are with them they never let you fight alone with your technical glitches.

As I use 2-3 accounts in my Outlook application, there were many files which were present multiple times and increasing the size of PST file. Finally, I used the Outlook duplicate remover tool which has a quite simple user-interface and did most of the work itself.

My Outlook mailbox was overloaded with duplicate emails and other data. Due to this, the size of the PST file exceeds more than 2GB. I thought that the file would eventually go corrupt. But when my colleagues recommended me this amazing software, it worked for life. All the duplicate data were removed from the mailbox, and the size of PST was optimized to a great level. Highly recommended!
