 @param [Hash] opts
 @option opts [Hash] :folder_shape The folder shape properties
   Ex: {:base_shape => 'Default', :additional_properties => 'bla bla bla'}
 @option opts [Hash] :sync_folder_id An optional Hash that represents a FolderId or
   DistinguishedFolderId.
   Ex: {:id => :inbox}
 @option opts [Hash] :sync_state The Base64 sync state id. If this is the
   first time syncing this does not need to be passed.
