unable to send email

Effective this pm (11/4/2017), receive message stating email message cannot be sent.  here is a sample: 

Message could not be sent to the following recipients:   (recipient removed by me)    (550 - 550 5.1.0 Authentication required
 
I have tried to send to several contacts, all get the same message.

Re: unable to send email

As a test try sending emails to those same people using another non-Comcast account you may have such as Yahoo or Gmail or something like that. Do those emails get through OK? The 550 error series normally means something is wrong with the recipient's email address.

Re: unable to send email

The Comcast/Xfinity email system was down which caused the problem, not the destination address.  Thank you for your response, it is good to know that someone was reading my post.  The system came back up within a few hours and has not gone down since.  I suspect the C/X system was being revamped or upgraded and therefore unavailable to their customers during that time as others posted a similar problem.
