Hi All,I am adding a contact that has the Yahoo ID in the following format firstname.lastname@example.orgYahoo comes back with 401 error.When I add a contact that does not have underscore character ('_') in the name it works. For example email@example.com can be added without problems.Do I have to do some character encoding on the special character?Can anyone help here? Thanks.Krassimir
