Error sending email: Reason: Sending failed. Please check your email settings and resend the invitation

hi everyone
My environment is tthe following
Debian 10
Ghost Version 5.49.2
Environment production
Database mysql
Mail SMTP
This is the current SMTP setup
“mail”: {
“from”: “research@",
“transport”: “SMTP”,
“options”: {
“host”: “smtp.office365.com”,
“port”: 587,
“service”: “O365”,
“secure”: false,
“requireTLS”: true,
“auth”: {
“user”: "research@
”,
“pass”: “***********”
}
}
}
Ghost is unable to send emails using Office 365.
In the logs I can see the following:
