I have a user complaining about a formatting issue with his outgoing HTML formatted messages. When he makes the message it is created in roughly the following format:

Greeting
[blank line]
Paragraph
[blank line]
Thank you

What he sees in his sent items and the internal recipient receives (I'm not sure about external recipients) is the following:

Greeting
Paragraph
Thank You

All of the white space gets removed when he is clicking Send. This is not happening with Plain Text... which the user is refusing to use. Any ideas as to why this is happening or what can be done to resolve it? I'm running GW 2014 R2 on the server and a mix of GW 2014 SP2 and 2014 R2 for clients and am seeing the same issue on both versions of the client. Thank you
