Hi 

I would like to create a simple rule

when a user sends a message with the subject "Project Summary" I want his manager to be added to the CC.

the manager is set for all users of the organization

Hello

tip:

That was super fast! thanks!

one last thing

do you know what will happen if the user does not have manager defined?

Hello

nothing.
exchange not discard email.

thanks

don't know how I missed this option but it was exactly what I needed
