This problem was noticed when I responded to one of my team member's emails (a lengthy response to a lengthy email).  The email, when received by my team member, was cut/truncated automatically by several lines.  We tried this over and over and it still would cut the lines off.

So, I copied and pasted the content into a new email and sent it - the fonts changed from Cambria to Times New Roman when my team member received it.  All emails were sent/received in HTML format.

Any fixes?
