Would there be any problems caused with setting up two owners of a mailbox or
calendar? Let's say for example, that I want to give someone permissions to
my mailbox or maybe specifically my calendar. I know there are publisher
options, etc, but what happens if I also set someone else up as owner? Does
Outlook get confused if we are both in the calendar at the same time or cause
any problems? Not sure why you would set up two owners.

Thanks!
