Our previous email provider used an unsecure SMTP at port 25. Microsoft Online uses TLS/SSL at port 587.

Server: smtp.mail.microsoftonline.com
Port: 587
Use SSL: checked
From: (our email address)
Reply To: (our email address)
Server Requires Authentication: checked
Username: (our email address)
Password: (our password)

Invalid token:
scRet: 80090308

Any help would be greatly appreciated!
