Here (using KMail against Exchange 2010 over IMAP) the attachment name 
is not mangled in your first message. OTOH, when I look at this message 
in OWA then the attachment name is mangled. It seems KMail is more 
forgiving.

For this mail the attachment name looks mangled on my system and in OWA 
which isn't surprising given that all non-ASCII characters seem to be 
encoded as %EF%BF%BD.

Content-Type: text/plain; 
name*=''D%EF%BF%BD%EF%BF%BD%20%EF%BF%BDst%20%EF%BF%BDin%20T%EF%BF%BDst%2Etxt
Content-Transfer-Encoding: quoted-printable
Content-Disposition: attachment; 
filename*=''D%EF%BF%BD%EF%BF%BD%20%EF%BF%BDst%20%EF%BF%BDin%20T%EF%BF%BDst%2Etxt
