I am not sure how I can better communicate my question. If you are having problems sending email, I need to know what you are using to send that email. There are different ways to access email on a computer. One way is to use a program to download or sync the email from the email provider onto the computer. One of these programs is called Outlook. Another way is to go to the website of the email provider, ie Hotmail.com, using a web browser like Internet Explorer or Chrome, to view the emails instead.
Where it gets kind of complicated is Hotmail was bought by Microsoft and used as their web platform. So now Hotmail.com redirects to login.live.com which is a Microsoft website. See this article for more info on the transfer from Hotmail to Microsoft(Outlook.com). Having problems sending from Outlook the program have different troubleshooting steps then having a problem sending from the website. Which do you use?
