Hi. I was using outlook2013 in windows 7 and there was no problem with that. Now, I am using Outlook2013 on my windows 8. All of my accounts work, except my university mail account which has POP3 SMTP server. I have enabled "My outgoing server require authentication" and that "this server require and encrypted authentication(SSL)" and used TLS for encrypted connection, according to the mail server help. But I receive the error of "the mail server responded:553 5.7.1". What should I do?
