I found the link below and the first code section works...it finds the email I need. I want to add to the code by 'Replying All' and adding the current workbook as an attachment.

I have tried to define the OutMail as an Outlook.MailItem so that I can access the properties of OutMail but when make that change and run it, I get a runtime error 13 Type Mismatch. Any suggestions?

For Each OutMail In OutFolder.Items

              i = i + 1
         End If
