If you can get the SMTP credentials of our Outlook (MS Exchange Server) then you use that to configure the email settings to send email.
I think you can use the below settings and try once.
user: 'YOUR EMAIL'
pass: 'YOUR PASSWORD'
On the majority of Exchange servers, Microsoft no longer supports basic credentials. Therefore, you must utilise Oauth2.0 for authentication, where in email connector you have the option to use
To enable OAuth 2.0 for Exchange Server, you must, however, do some Azure AD configurations. For additional information, see the email connector documentation.
OR, use the above mentioned settings if basic credentials are still supported.
