Laravel sending email with Office 365 Email

We've changed from gmail to office 365, but the issue: Client does not have permissions to send as this sender 550 when sending email.

Do we have any configuration in office 365 mail service to enable sending email from website/application?

This is my .env configuration:

MAIL_DRIVER=smtp
MAIL_HOST=smtp.office365.com
MAIL_PORT=587
MAIL_USERNAME=mail_username
MAIL_PASSWORD=mail_password
MAIL_ENCRYPTION=tls
