I've been trying to write macros that, e.g., assign tasks to others.

However, since I am on a single user PC, how do I fool Outlook into believing that I am not sending the email to myself?

Do I need a separate internet email account for each user?

Can I fake it by using the same email account for two different users on my PC, i.e., I can CTRL ALT DEL and log in on the PC under a different account?
