outlook update meeting request no response to text

If the organizer chooses to send an update to existing attendees, the attendees receive the update as an informational update. The newly added attendee receives the meeting request as a new request. If an organizer adds an attendee to a prior meeting request, the organizer must send the meeting request to the newly added attendee, and has the option to include existing attendees on the update. If an attendee already accepted the initial meeting request, the attendee receives the update as an informational update.

If an organizer changes the location of a prior meeting request, the organizer must send an update to all the attendees. In these scenarios, responding to the informational update is optional. There are four scenarios in which Outlook generates an informational update. If an attendee has not responded to an initial meeting request and receives a subsequent update, the initial meeting request becomes out-of-date and the update is a full update, regardless of the cause of the update. This update is a full update to which an attendee must explicitly respond to notify the organizer of attendance, because Outlook ignores any previous responses. When an organizer changes the date, time, time zones, or recurrence of a prior meeting request, the organizer must send an update to all the attendees. There are two scenarios that result in a full update: A full update requires an attendee to explicitly respond to the meeting request, and an informational update does not. Any subsequent update of that meeting is either mtgFullUpdate (a full update) or mtgInfoUpdate (an informational update) depending on the cause of the update, with Outlook setting PidLidMeetingType accordingly. When Outlook receives a new meeting request, Outlook sets the PidLidMeetingType property of the meeting request item to mtgRequest. Programmatically, Outlook sets the named property PidLidMeetingType of a meeting request to identify the current update status. Outlook supports setting up delegates who can respond to meeting requests on behalf of the principal recipient. By default, an attendee receiving a meeting request responds to it directly. A meeting request is an email that has as the message class.
