x-post? How do you use it from outlook?

You can't crosspost with Outlook, since Outlook doesn't read newsgroups.
You can't make any posts to newsgroups with Outlook. "X-post" is another
way of saying "crosspost" and this message, like the one you posted, is
already crossposted to m.p.outlook.calendaring and m.p.sharepoint.general.
