How to add my Outlook email signature to the COM o

Question

I am working RDCOMClient into some of my work flow and thanks to agstudy's answer Here I am able to send emails throuhg r, but I can't figure out how to add my Outlook email signature. I'm new to COM objects, but have done a fair share of searching and haven't found anything. Because my reputation hasn't hit 50 yet, I wasn't able to comment on the inital thread to ask there. Can someone show me how I can add my Outlook email signature?

library(RDCOMClient)
OutApp <- COMCreate("Outlook.Application") 
outMail = OutApp$CreateItem(0)
outMail[["To"]] = "[e-mail]"
outMail[["subject"]] = "some subject"
outMail[["body"]] = "some body"
## I want to add my outlook signature here.                     
outMail$Send()

Consider using Outlook's GetInspector() property. Assuming you have an auto-signature, assign a variable to capture the default body and then concatenate to your latter message:

library(RDCOMClient)

olMailItem = 0
OutApp <- COMCreate("Outlook.Application")
outMail <- OutApp$CreateItem(olMailItem)

outMail$GetInspector()
signature = outMail[["HTMLBody"]]

outMail[["Recipients"]]$Add("[e-mail]")
outMail[["Subject"]] = "some subject"
outMail[["HTMLBody"]] = paste0('<p>some body', signature, '</p>')

outMail$Display()
outMail <- NULL
OutApp <- NULL
