scott, I had a similar misconception about Outlook and Method. Right now I have Method set up to use its own templates and attach its generated reports, and to send within Method. I have this email BCC to myself so I can view it in Outlook later.
But what I would really love is to be able to click a "send email" button in Method, and have an Outlook email window pop up, with the template inserted and the generated report PDFs attached, like how Quickbooks does it. This allows us to view and change attachments, keep track of sent emails in the Outlook "sent" folder, and take advantage of all the specialized email features Outlook offers. Join me in requesting this feature!
