Keep formatting of Outlook signature when creating mail

问题

I copied the whole block of code from How can I use Outlook to send email to multiple recipients in Excel VBA and added a signature at the end of the email message.

With OutMail
    .Display
End With
    Signature = OutMail.Body
With OutMail
    .To = sTo
    .CC = sCC
    .BCC = ""
    .Subject = Worksheets("MassEmail").Range("A2") & " WW" & Worksheets("MassEmail").Range("B1")
    sHTML = "<HTML><BODY><FONT face=""Calibri, Arial"">"
    sHTML = sHTML & "<p style=""font-size:11pt"">Hi,</p>"
    sHTML = sHTML & "<p style=""font-size:11pt"">Here is the RMA list WW" & Worksheets("MassEmail").Range("B1") & ".  Please review.</p>"
    sHTML = sHTML & "<pre style=""font-size:11pt;font-family:Calibri,Arial"">     Total: </pre>"
    .HTMLBody = sHTML & Signature
    .HTMLBody = .HTMLBody & "</FONT></BODY></HTML>"
End With

This is how the signature should look.
