WYSIWYG Html Editor in Outlook 365 issues.

I am using the timymice wysiwyg html editor

The attached code works everywhere EXCEPT when send to a desktop email client like MS Outlook 365.

In any browser based app it looks fine

This is the timymice code

Also attached is the html and screen print of the "flawed" Outlook smtp delivered version

I have been going round and round in my .net app trying to resolve this.

I save to server... saves fine
Pulls fine
