The fix for Outlook Classic
Pre-render transformed states as images or use table layout
The engine still flags this in the fix: An image points to an address no inbox can load (rotated-content.png), so Outlook Classic shows a broken image instead.
<!-- Pre-render rotated content as an image -->
<img src="rotated-content.png" width="200" height="200"
alt="Rotated content"
style="display: block; border: 0;" />Show the original
<div style="transform: rotate(45deg);">
Rotated content
