This option is not compatible with Microsoft Security Defaults or multi-factor authentication (MFA). If your environment uses Microsoft Security Defaults or MFA, we recommend using Option 2 or 3 below”.

$. the option 2 and option 3 are “Option 2: Send mail directly from your printer or application to Microsoft 365 or Office 365 (direct send)” and “Option 3: Configure a connector to send mail using Microsoft 365 or Office 365 SMTP relay”.

4. We use option 2 fixes the problem. Here is the settings
