Hi there, @skaul. Thanks for posting on YesCrowd!
If you're getting this error when trying to use your OptusNet webmail account on Outlook, I'd recommend checking our guide on Using an email application with OptusNet email
Generally, your settings should match these:
Host: smtp.optusnet.com.au
Username: Your email @OPTUSNET.com.au
Password: Your Optus net email password.
Server Port: 25 (no SSL) or 465 (with SSL)
Let us know how you go!
