When you use the Hosted Exchange service you usually use the MAPI or Outlook anywhere protocol but if you need to use the SMTP protocol, here are the configurations that you must use.
Remember that the SMTP service is necessarily authenticated.
These are the parameters to indicate:
Host: mail.utixo.eu
user: account (without @ domainname.est)
pass: the password in this possession
port: 587
authentication: yes
