I have a user that invited an external client on Exchange, per
<meta name=3D"Generator" content=3D"Microsoft Exchange Server">

But the instances declined do not show up on the Zimbra user's calendar anywhere. The message just displays the text message from the person declining. The decliner's message has a base64 encoded message which I am guessing cannot be parsed?

Code:
<font face=3D"Calibri" size=3D"2"><span style=3D"font-size:11pt;">
<div>Donald, I will be traveling en route to North Carolina and will thus m=
iss this session.&nbsp; </div>
<div>&nbsp;</div>
</span></font>
</body>
</html>
