If I open the saved .msg file I see the following:
<META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=Windows-1252"> <META NAME="Generator" CONTENT="MS Exchange Server version 6.5.7654.12"> <TITLE>Henry Jacobs & Associates Appt</TITLE> </HEAD> <BODY> <!-- Converted from text/plain format -->
Why would this be happening if the email is composed in HTML format and should be sent as such? I assume the above means that MS Exchange Server is modifying the message.
After the message is sent it appears correctly in the users Sent Items folder, additionally if it is sent to another exchange user it keeps the correct formatting. However, if the message is sent to an email address that is not internal to the exchange server then the message appears as plain text instead of html formatted.
