I resolved my issue through a lot of trial and error. I looked at the Server logs, some of email ID's were not being validated. I re-entered all of the ID's because it appeared that maybe some spaces might have been generating an invalid email address. I always use a semicolon to separate the addresses with the exception of the last address. Turns out if I add the addresses in a single string email1;email2;email3; then hit the carriage return after including the semi colon for the last address and then hit the apply button the chance of a blank or unnecessary characters was eliminated. All addresses validated and I was good to go...
It appears that the dialog for adding addresses is a bit touchy.
Problem solved and thanks for your response.
