Personalized meeting invitations, which may be used by electronic calendar applications (which may also be referred to as “calendar applications”, “calendaring applications”, or “calendar scheduling systems”). Using techniques disclosed herein, a meeting can be conceptually viewed as multiple smaller meetings, which are also referred to herein as “submeetings”, and a personalized meeting invitation sent to each invitee reflects that invitee's required presence at the meeting or an individual submeeting thereof. Optionally, personalized meeting invitations may also be used for invitees whose presence at a submeeting is optional. When an invitee accepts a personalized meeting invitation, the submeeting is placed on the invitee's electronic calendar, showing the invitee as unavailable during the corresponding time slot for the submeeting. Other people viewing the invitee's calendar can then see an accurate view of the invitee's availability.
