Explanation
The correct sequence of steps that should be performed is:
Step 1 = Use a Take Screenshot activity to capture the state of the machine. The output is an Image variable, for example img_screenshot.
Step 2 = Use a Save Image activity to save the image to a local file. Supply the FileName (e.g.
screenshot.png) and the Image property should be the variable created in step 1.
Step 3 = Use a Send Outlook Mail Message activity to compose and send the email. Configure the Attachments property to include the file path of the image saved in step 2 (e.g. "C:\Users\username\screenshot.png").
Step 4 = Optionally, use a Delete File activity to delete the image file from the local drive after sending the email. Supply the Path property with the same file path as in step 3.
