I'll try to simplify this scenario as much as possible as our complete use-case is a bit complicated.
On our Case form we have a lookup field to an email record. I also have a workflow that sends an email to the Contact. In the body of the workflow's email I display the Description field from the lookup email. What I've found is if the lookup refers to an HTML email that was received from Outlook, the outbound email from the workflow will show Font Definitions and Style Definitions when it's received by the Contact. The email message within CRM doesn't show this, though.
Example:
/* Font Definitions */
@font-face
{font-family:PMingLiU;
panose-1:2 2 5 0 0 0 0 0 0 0;}
@font-face
{font-family:"Cambria Math";
panose-1:2 4 5 3 5 4 6 3 2 4;}
@font-face
{font-family:Calibri;
panose-1:2 15 5 2 2 2 4 3 2 4;}
@font-face
{font-family:"\@PMingLiU";
panose-1:2 2 5 0 0 0 0 0 0 0;}
/* Style Definitions */
p.MsoNormal, li.MsoNormal, div.MsoNormal
{margin:0in;
margin-bottom:.0001pt;
font-size:11.0pt;
font-family:"Calibri",sans-serif;}
a:link, span.MsoHyperlink
{mso-style-priority:99;
color:#0563C1;
text-decoration:underline;}
a:visited, span.MsoHyperlinkFollowed
{mso-style-priority:99;
color:#954F72;
text-decoration:underline;}
span.EmailStyle17
{mso-style-type:personal-compose;
font-family:"Calibri",sans-serif;
color:windowtext;}
.MsoChpDefault
{mso-style-type:export-only;
font-family:"Calibri",sans-serif;}
@page WordSection1
{size:8.5in 11.0in;
margin:1.0in 1.0in 1.0in 1.0in;}
div.WordSection1
{page:WordSection1;}

I tried researching this and a few online articles said this was an issue with older versions of Outlook and that upgrading to Outlook 2013 would solve the problem. However I am using Outlook 2013. My guess is CRM's email editor/router doesn't know what to do with this Font and Style definitions information. Does anyone have any ideas on how to get rid of it? I can only think to check the beginning of the Description field to see if it begins with this text and then just delete it.
