When you mentioned a composing message, I thought you meant a message that was being composed and was not in the message store. In that situation you can use tokens as suggested.

When you are creating a message programmatically and with no user interface, you really need to use the RTF (Rich Text Format) property of the message body text to get the desired results. It’s a little more difficult to do, but here’s a simple example. Note I have greatly simplified the RTF code in this example:

Sub Main(Client, GWEvent)

  dim iBody
  
  iBody =   "{rtf1ansiansicpg1252uc1 {This is plain" &_
            "par" &_
            "par This is }{b bold}{" &_
            "par This is }{i italics}{" &_
            "par }}"


' Create a email message
  Set NewMsg = GroupWise.Account.MailBox.Messages.Add("GW.MESSAGE.MAIL", 4)
  
  ' Add a recipient 
  MsgRecipient = NewMsg.Recipients.Add(GroupWise.Account.Owner.EmailAddress,,0) 
  
  ' Subject and body text of the mail
  NewMsg.FromText = GroupWise.Account.Owner.DisplayName
  NewMsg.Subject = "System Störung"
  NewMsg.BodyText.RTF = iBody
  NewMsg.Send
     
End Sub

I hope this helps.
