April 7, 2016 I was using Windows Live mail 2011, all of a sudden I could receive but not send emails.

I upgraded from Windows Live Mail 2011 - 2012. It seemed the problem was fixed.

Now I can send a receive individual email, but I cannot send a group email to 600 people.

I have never had this problem until Thursday.

I am using a bellnet.ca email address. My operating system is Windows 7

Can anyone tell me why and help me out with this problem. It is a real problem if I can't send out a group correspondence.

Thank you
