On a computer running Windows 7 when you start Outlook Express mail said that would be nice to compress folders and user agreed. During compression, there was an error File in Use, then the folder Inbox is missing some of the letters. Usually during compression creates a file with the extension .bak, but in this particular situation it is not created. Attempted to restore letter program Recovery Mailbox - she does not see the missing letters. Tell me, which of the existing programs to restore dbx-files suitable for solving my problem?
