To set up Infusion with the oAuth2 Protocol, go to Admin / Defaults / Manage Email Defaults, select the option Office 365 (oAuth2) and enter your credentials.
The Test Now button can be used to check if the credentials are correct and working – you may be redirected to the Office365 login page to sign in first.
Your firewall may also block the communication and you will need to allow access.
This feature does not support sending emails from a report preview.
