This morning I have opened my MS Outlook and was amazed reason of all my emails were lost. I tried to restore, but I couldn't. Luckily for me I entered in the Internet and noticed a tool - mailbox.pst repair (http://www.recoverytoolbox.com/pst_mailbox_repair.html). It solved my trouble for seconds and free of charge as I bore in mind. Moreover the program showed me how it could process corrupted *.ost and *.pst files, it is safe, even if your mailbox is infected.
