I can receive but not send emails. (I keep getting error code 0x80042109). What should I do?

The most common cause of this error message is a problem with connecting to the internet and account settings configured incorrectly in Outlook. First, make sure that you are connected to the internet. If your email is with us, check your server settings are as below:

POP setting

  • Server name: outlook.office365.com
  • Port: 995
  • Encryption method: SSL

SMTP setting

  • Server name: smtp.office365.com
  • Port: 587
  • Encryption method: SSL/TLS
