Programmatically change font properties in email body - vba

Question

I have been successfully programming this in PowerPoint VBA but haven't been able to make it work on Outlook.
I have an email ready to be sent in Outlook 2013
I want to scan the body of the email for bold text (i.e., bold characters) and change its color to red
(nice to have) Exclude from the macro the signature
I tried several attempts with "Substitute", "if"-loop but no success. Thanks a lot for putting me on the right track.
The following code converts the color of the body but does not discriminate for bold words. Any ideas?
Public Sub FormatSelectedText()
Dim objItem As Object
Dim objInsp As Outlook.Inspector
' Add reference to Word library
' in VBA Editor, Tools, References
Dim objWord As Word.Application
Dim objDoc As Word.Document
Dim objSel As Word.Selection
On Error Resume Next
'Reference the current Outlook item
Set objItem = Application.ActiveInspector.CurrentItem
If Not objItem Is Nothing Then
If objItem.Class = olMail Then
Set objInsp = objItem.GetInspector
If objInsp.EditorType = olEditorWord Then
Set objDoc = objInsp.WordEditor
Set objWord = objDoc.Application
Set objSel = objWord.Selection
' replace the With block with your code
With objSel
' Formatting code goes here
'.Font.Size = 18
If .Font.Bold = True Then
.Font.Color = wdColorBlue
End If
.Font.Color = wdColorRed
'.Font.Italic = True
'.Font.Name = "Arial"
End With
End If
End If
End If
Set objItem = Nothing
Set objWord = Nothing
Set objSel = Nothing
Set objInsp = Nothing
End Sub

Answer 1

First of all, I'd suggest starting from the Getting Started with VBA in Outlook 2010 article in MSDN.
You can use the HTMLBody property of Outlook items to get the HTML content of the message body or use the Word object model to get the job done. The WordEditor property of the Inspector class returns an instance of the Document class from the WOM (Word object model). See Chapter 17: Working with Item Bodies for more information.
