Access type:


To provide any of the store functionality, the store provider must implement IMAPIProp : IUnknown and return a valid property tag for any of these properties passed to an IMAPIProp::GetIDsFromNames call. When the property tag for any of these properties is passed to IMAPIProp::GetProps, the store provider must also return the correct property value. Store providers can call HrGetOneProp and HrSetOneProp to get or set these properties.

To retrieve the value of this property, the client should first use IMAPIProp::GetIDsFromNames to obtain the property tag, and then specify this property tag in IMAPIProp::GetProps to get the value. When calling IMAPIProp::GetIDsFromNames, specify the following values for the MAPINAMEID structure pointed at by the input parameter lppPropNames:







A store provider that uses a server to send meeting updates can modify the Send Update to Attendees dialog box. This functionality is useful because when the server sends a meeting update, the server does not know which attendees have been added or deleted by the user since the initial meeting request. When this property is true, the Send update only to added or deleted attendees option is not displayed in the Send Update to Attendees dialog box.

This property is ignored if the version of Outlook is earlier than Microsoft Office Outlook 2003 Service Pack 1, or if its value is false.
