One of my friends suggested me to try OST Reader freeware software, which made me view OST file data. Now, I am able to open the file and browse through different mails and other data items. Thanks to development team for such a great OST Explorer tool."

OST Viewer is good software for viewing all emails, contacts, calendars from orphaned or disconnected Outlook OST file. It is really an amazing tool, because i was able to view my data from a corrupted OST file too. Cause of this feature I have been a fan of this tool.
I have used many tools for viewing emails from OST file, some of the tools were paid and some were free to use. But I found that the OST file Viewer is more effient and accurate software for opening OST file emails.
