Sucks big time. Not only Linux users get pissed but also Macintosh users. Of course you can open it as long as you know how. On Mac OS X you need <a href="http://www.joshjacob.com/macdev/tnef/" target="_blank" rel="noopener noreferrer nofollow">TNEF’s Enough&nbsp; <svg class="svg-inline--fa fas fa-up-right-from-square fa-2xs" fill="currentColor" aria-hidden="true" role="img" viewBox="0 0 512 512" overflow="visible"><use href="#fas-up-right-from-square"></use></svg></a> and on Linux you need <a href="http://ytnef.sourceforge.net/" target="_blank" rel="noopener noreferrer nofollow">tnef&nbsp; <svg class="svg-inline--fa fas fa-up-right-from-square fa-2xs" fill="currentColor" aria-hidden="true" role="img" viewBox="0 0 512 512" overflow="visible"><use href="#fas-up-right-from-square"></use></svg></a> . Suse Linux 9.2 has an rpm that works well with KMail. Just click the winmail.dat and select &ldquo;Open with tnef&rdquo;. You will get the list of attachments that are hidden in the winmail.dat attachment and you can open and/or save them from there.</p>
