html - Possible to execute JavaScript in Outlook calendar? -

is possible execute javascript in outlook calendar?

i created outlook invite , modified icalendar file. added header section of x-alt-desc property:

<script type="text/javascript"></script> 

and body section:

<a href="#" onclick="function hi(){alert('hi!')};hi()">click</a> 

when viewed modified outlook invite, “click” displayed nothing happened when clicked on it. seems javascript not executed. perhaps outlook software not contain code execute javascript? note: outlook contain code interpret html, interprets html in x-alt-desc property.
