I've created a workflow which creates, executes and then deletes a Visual Basic Script file. The VBS file contains a script which interacts with Outlook, creating a new email and displaying it, this can also be changed to simply send the email, notes inside the workflow. Important: Upon the completion of the workflow (file is written) there is an event which is triggered that executes the file using cscript.exe. The next step is to add an attachment to it. Feel free to contact me in case of questions/improvement suggestions.
