hotmail on s2 stopped working

Unless you need the emails that are currently on your phone, the easiest solution is to delete your hotmail account on the phone, turn the phone off, turn the phone on and create a hotmail account on the phone (using the same email address, pssword, etc.)

If you can't do that, Hotmail settings are published on the web. The IMAP settings are

• Server Name: imap-mail.outlook.com
• Port: 993
• User Name: your username (for example j.kowal@outlook.com)
• Connection security: SSL/TLS
• Authentication method: Normal password

The SMTP settings are

• Server Name: smtp-mail.outlook.com
• Port: 587
• Connection security: STARTTLS
• Authentication method: Normal password
• User Name: your username (for example j.kowal@outlook.com)
