What Clients Say about SYSDaddy OST Reader Software

On my Office PC with the Microsoft Windows 10 operating system, everything worked fine with Outlook 2016 and Exchange Server. All of a sudden I don't know what happened, that I lost all my access from the source email client. I restarted all associated applications on my computer, but nothing worked. Luckily I had this Microsoft OST viewer tool on my personal laptop which actually saved my life. I was able to work with some core emails that I had to write a project report on and present to my managers by the next morning.

Kind regards to the development team of this freeware. I really appreciate the hard work and mindset the developers considered in creating this product. If I explain my reason for using this free Microsoft OST file viewer, it would surely be a one-sided review. So, to keep my words short, I want to say that this product eliminates all of the problems an investigator faces when having to view data from orphaned OST files. This is the perfect app to view ost files from the latest Microsoft Outlook versions on the Windows platform for free.
