I downloaded the trial version of DataNumen Outlook Password Recovery (not to be mistaken with Outlook Repair or Outlook Drive Recovery) and started the recovery process, but cancelled the operation just after it had begun so that I could copy the encrypted pst file to a different location to be sure I had a backup (forgetting I had a backup already in my Outlook Files directory). But I forgot the password for an encrypted pst file containing 14.5 GB of email and attachments (about seven years of email, some of which is extremely important to me). That computer died, though fortunately, I was backing up all my files (including Outlook pst files) onto an external drive. I was using Outlook 2010 on my last computer, which ran Windows 7.
Excellent program, and excellent customer support (among the best customer support I have experienced).
