<p dir="auto">If it has been the case this long, pretty sure Benny, the developer has known about it as has M$ (Microsoft).</p>
</blockquote>
<p dir="auto">Benny knows A LOT. Unfortunately, not enough people pay for MM to support him hiring help, or at least that is the impression I've gotten.</p>
<p dir="auto">Microsoft knows NOTHING about 3rd-party mail clients. They don't care, except when given an opportunity to degrade the experience of using non-MS software.</p>

<p dir="auto">As to why they each made that conscious decision is up to the respective developers, I’m betting it was a conscious one on each of them. Mailmate shouldn’t be responsible for unique non-standard server’s, that’s a slippery slope in my opinion.</p>
</blockquote>
<p dir="auto">Agreed. It's an easy workaround for those cursed with Exchange to either ignore the dupes or use a MM rule to hide them.</p>
<p dir="auto">I <em>thought</em> that Benny had provided a new 'defaults' pref to disable saving a copy of sent messages to the Sent mailbox, but I can find no such conversation now...</p>
</blockquote>
<p dir="auto">Benny did provide a workaround of sorts; look here: <a href="https://freron.lighthouseapp.com/projects/58672/tickets/2145-do-not-store-copies-in-sent-messages#ticket-2145-32" style="color: #3983C4;">https://freron.lighthouseapp.com/projects/58672/tickets/2145-do-not-store-copies-in-sent-messages#ticket-2145-32</a></p>
<p dir="auto">I've been using this workaround for years. In addition to setting some other mailbox as the Sent Messages folder, I went in to the account settings and unsubscribed from Exchange's Sent Items folder.</p>
