allow Outlook appointments that are busy for you but free for others - good for vacation notices/reminders
One way my team shares vacation information is creating appointments and inviting key contacts to serve as a reminder. If you set it to appear as busy to prevent being invited to meetings, it shows up as busy on everyone else's calendar. If you set it to appear as free, it doesn't stop people from inviting you to meetings during your vacation. It would be nice to have an option of creating an appointment that's busy for you but can be set to appear as free for anyone you invite.
