[Mahmoud-S-Ahmed]

Hello,

I have created a free outlook account to test oauth2-proxy. Authentication is done correct but I am getting the below error when I try to send an email:
535 5.7.139 Authentication unsuccessful, SmtpClientAuthentication is disabled for the Mailbox. Visit https://aka.ms/smtp_auth_disabled for more information

Below is the configuraiton:
permission_url = https://login.microsoftonline.com/common/oauth2/v2.0/authorize
token_url = https://login.microsoftonline.com/common/oauth2/v2.0/token
oauth2_scope = https://outlook.office.com/IMAP.AccessAsUser.All https://outlook.office.com/POP.AccessAsUser.All https://outlook.office.com/SMTP.Send offline_access
redirect_uri = http://localhost
client_id =
client_secret =

Thanks
