    Office365 only supports tls secure email or you need to setup a mail connector ie mail relay in Office 365

    Are you trying to send using the customer's Office 365 as the SMTP server or are they just the final destination? If the latter, is there any additional information after the code 550 such as "email blocked" or "denied by policy"? Both might be corrected by having the customer white list the sender you are using. You may also want to contact Go Daddy ans ask why their server has been black listed by Office 365.

    I always have trouble using office 365. The customer or their IT may have to help you and call Office 365 to get support so that it will send from Office 365 smtp server. Otherwise if its not a problem with the customer where the email is coming from you should be able to create a gmail or mail.com email and it will send. I use mail.com for a lot of the older machines that don't support TLS

    Set up a SMTP2go account for the device. Use a domain that is not the one you are sending to eg your own domain.
    It's best practice to turn off smtp on Office365, and smap filtering will block a masked domain in office365 or an address that is not in the directory. If you have any questions on this pm. Me a we can Skype to discuss

    Usually with Office365, the sender's name must be the same as the email address used for authentication. I think that will pop a 550.

    There were a number of online email services that used to reject incoming emails when the sender's domain and the authentication domain did not match.
