The EntryID property is not set for an Outlook item until it is saved or sent. Read-only String.

Example

This example compares the entry ID of one message to the entry ID of a message returned by a search operation to determine whether the objects represent the same message.

If myItem.EntryID = myFoundItem.EntryID Then
    MsgBox "These two message objects refer to the same message."
End If
