How do I highlight text in a message body with VBA?

Hello,

My task is to compare the bodies of two messages using VBA and highlight the text of the second message where the values are different. I am using the following code to split the lines of the message bodies into string arrays using the Split function and then loop through the lines and compare them. I am attempting to enclose each line with <div> tags and apply a style to change the text color. I later set the BodyFormat property to olFormatHTML when I send the final message but the resultant markup is displayed in the message. Is there another possible solution to this problem?
Dim beginRedDiv As String, beginBlackDiv As String, endDiv As String
    beginRedDiv = "<div style='color:red;'>"
    beginBlackDiv = "<div style='color:black;'>"
    endDiv = "</div>"
    
    Dim oldUpdateMessageBody() As String, newUpdateMessageBody As String, newTranscriptionMessageBody() As String
    
    oldUpdateMessageBody = Split(OriginalMessage.Body, vbCrLf)
    newTranscriptionMessageBody = Split(mUpdateMatchMessage.Body, vbCrLf)
    
    Dim i As Integer
    For i = 0 To UBound(oldUpdateMessageBody)
        If oldUpdateMessageBody(i) <> newTranscriptionMessageBody(i) Then
            newUpdateMessageBody = newUpdateMessageBody & beginRedDiv & oldUpdateMessageBody(i) & endDiv
        Else
            newUpdateMessageBody = newUpdateMessageBody & beginBlackDiv & oldUpdateMessageBody(i) & endDiv
        End If
    Next

I seem to have found the solution on my own. I just needed to dig a little more. It seems all I needed to was use the HTMLBody property of the final message instead of the Body property. My text is now colored appropriately.
