Schedule meetings and send invitations?

[itguy1971owp]

what's the best way you've found to schedule a meeting and send invitations? Also, to update the invitation?

When I create a meeting on the website it doesn't seem to send out the invitations.  Meetings are being missed.  It used to work "okay", but not anymore.

What's your process?  Also, how do you verify the meeting was received or accepted?  

I apologize if this has been addressed before.
