The answer is <a target="_blank" href="https://apple.stackexchange.com/questions/138537/how-can-i-delete-my-mail-app-and-re-install-it">here</a>, but I wanted to post with something that would catch Google searches, since none of mine today worked until I was trying to delete <code>Mail.app</code> all-together to re-install it (which you can't really do).
<hr />
But, just run:
<pre><code class="lang-bash">killall Mail &amp;&gt; /dev/null; mv ~/Library/Containers/com.apple.mail/Data/Library/Preferences/com.apple.mail.plist ~/Desktop &amp;&amp; open -a Mail
</code></pre>
If it works, delete the <code>com.apple.mail.plist</code> file on your Desktop!
...it worked on my machine ;)
I did have to re-set all my Mail.app settings again, but worth it!
