The DelegateEntryId property returns a list of mail entry identifiers for delegates.
Schedule object
String (multivalued)
Read/write
Only the owner can write to the DelegateEntryId property � everyone else has read-only access. This property is used to assign delegates for the schedule�s owner. Because the property is multivalued, you can set it to any number of delegate entry identifiers. When a meeting request is received, each delegate in this property will receive meeting requests on behalf of the schedule�s owner.
This property must reflect the delegates specified in the AccessControls table. The values of this property should only be changed by the Schedule+ user interface.
