Sending Email from O365 SMTP Server in Azure

Hi all, we got an authentication error by sending email. We use O365 in Azure, smtp.office365.com port:587. 

In the Dev Environment Service Center we have:

SMTP Server: smtp.office365.com

SMTP Port: 587

Username: <an currently user from O365>

Password: <password>

Then we got this error: "Error sending email 24021: 535 5.7.3 Authentication unsuccessful [AM5PR602CA0009.EURP189.PROD.OUTLOOK.COM]"

Screenshots are attached.

Have you an idea  what is the issue?

Thanks for any help.

Hi Carla,

That error message is coming from Office 365, not OutSystems. A quick google shows various articles that deal with this problem, but I can't assess which of these could help you, so please google yourself.
