Outlook users may sometimes request a delivery receipt or a read receipt when sending a message. 

Typically, when reading said email, the user will be prompted to send the receipt; if we are using ProcessRobot/WinAutomation to read emails from Outlook, the prompt will appear, but the process will be unable to handle it, since it will be executing the "Retrieve Email Messages from Outlook" Action at the time - the process will hang on that action until it crashes, or the user intervenes.

A way to handle this scenario is to create a second Process, which will handle this prompt independently. 

This process will be called from within the initial one, and wait until the popup appears; once it does, the secondary process will handle it, and the initial one can continue with its execution.
