When Microsoft Office Outlook receives a meeting request item (which is an e-mail of message class IPM.Schedule.Meeting.Request), Outlook creates and sets this property for the item. The possible values of this property for a message which is a meeting request item are the following:

ValueStatus of Meeting RequestDescription
mtgNoneNoneOutlook has not set this property for the message.
mtgRequest NewMessage is a new meeting request.
mtgFullUpdate Full updateMessage is a full update of a prior meeting request.
mtgInfoUpdate Informational updateMessage is an informational update of a prior meeting request.
mtgOutofDate Out-of-dateMessage is out-of-date and a more recent update has been sent to the recipient.
mtgDelegated DelegatedMessage is a copy of a meeting request, or a copy of an update of a prior meeting request received by the principal recipient. The original meeting request or the update has been sent to a delegate of the principal.

When Outlook receives a new meeting request, Outlook sets the dispidMeetingType property of the meeting request item to mtgRequest. If the recipient accepts the meeting request, any subsequent update of that meeting is either mtgFullUpdate (a full update) or mtgInfoUpdate (an informational update), depending on the cause of the update. A full update requires the attendee to explicitly accept the meeting request again, and an informational update does not. For more information about informational updates and full updates, see About Meeting Requests as Informational Updates and Full Updates.

If the recipient has not accepted an initial meeting request and receives a full update or an informational update, then Outlook assigns the dispidMeetingType property of the initial meeting request as mtgOutofDate, and the second meeting request mtgFullUpdate.

If a recipient has one or more delegates, delegates receive meeting requests and updates on behalf of the principal. Outlook sends the original meeting request or meeting request update to the delegates. And, by default, Outlook sends only a copy of these requests to the principal; these copies have dispidMeetingType set to mtgDelegated. An exception is when the message is marked Private. In this case, Outlook sends the message to only the principal; private messages have dispidMeetingType set to mtgRequest, mtgFullUpdate, or mtgInfoUpdate as appropriate.
