 @param [Hash] opts
 @option opts [Boolean] :save_item_to_folder To save or not to save... save! :-)
 @option opts [Hash] :saved_item_folder_id A well formatted folder_id Hash. Ex: {:id => :sentitems}
 @option opts [Array<Hash>] :item_ids ItemIds Hash. The keys in these Hashes can be
   :item_id, :occurrence_item_id, or :recurring_master_item_id. Please see the
   Microsoft docs for more information.
 @example
   opts = {
     :save_item_to_folder => true,
     :saved_item_folder_id => {:id => :sentitems},
     :item_ids => [
       {:item_id => {:id => 'id1'}},
       {:item_id => {:id => 'id2'}},
     ]}
