I am trying to setup the ability to send emails using my Office365 email account from my .net site. Before i code this, i want to make sure its possible to do so and hence using a SMTP debugging tool i got from the internet. I keep getting 504 5.7.4 Unrecognized authentication type error.
Settings:
server: smtp.office365.com
Port: 587
User: myemail@mysite.com
Pass: mypassword
Requited Authentication: true
From Email: myemail@mysite.com
To Email: User: myemail@mysite.com
When i post this request i get the following logs:

What i have tried I read that outlook has "Security Defaults" that blocks SMTP. I have turned this off.
What might be going wrong?
