These emails are created when Outlook internally generetas them. For example a message from Office Communicator which states "Missed conversation with somebody, somebody else, etc". If one the names contains chars with umlauts it's simply encoded in UTF8 without specifying so. There are emails sent from other Outlook clients via same Exchange server too, which have UTF8 subjects when they contain for example umlauts. > > It is highly unlikely > > that > > all your malformed emails are in utf-8.

An awk script with a pipe to a shell script that does the charset check and converts to quoted printable format using mmencode. I have a solution. If you ever do something similar then make sure to convert the Subject: header in the header of the main email message only. You'll find loads of UTF8 subjects in the messages itself as Outlook usually quotes inline starting with the "-----Original Message-----" line and then quoting the To, From, Sent and Subject headers which are in UTF8, but that's OK as they are in the body of the message. libpst should do this IMHO, but I'm not versed in C to actually write a patch.
