OFFICE365 ISSUES

[RafalBor]

Hi,
I've followed some tips on the forum and activated SMTP Authentication, removed MFA, disabled self-service reset, but still getting issue upon sending e-mail notification as listed below. Not sure where in Office365 admin panel should now look to facilitate e-mail sending.

* arg: 1
  * nil
* arg: 2
  * string: 535 5.7.139 Authentication unsuccessful, SmtpClientAuthentication is disabled for the Tenant. Visit https://aka.ms/smtp_auth_disabled for more information. [LO2P265CA0480.GBRP265.PROD.OUTLOOK.COM]

Yes, got the same link once searching, but no luck here

All sorted,

if anyone would have similar issue - then you need to switch off default policies and create for each individual account (user/tenant) policies for apps and for authentication. then must create bypass any authentication rule for user used at Logic Machine e-mail notifications
