Questions Regarding SSO Setup via Microsoft 365 and Email Listener Integration

Hello,

Our customer has a requirement to log in using SSO via Microsoft 365, and I have a few questions regarding this.

1. Does Creatio support SSO via Microsoft 365? I came across an article about setting up SSO via Microsoft Entra AD (https://academy.creatio.com/docs/8.x/setup-and-administration/administration/user-and-access-management/authentication/set-up-sso-via-azure-ad). In this case, is "Microsoft Entra AD" the same as "Microsoft 365"?
2. For an on-site environment, is it necessary to set up the MS Exchange integration service (https://academy.creatio.com/docs/8.x/setup-and-administration/on-site-deployment/containerized-components/email-listener-synchronization-service) before configuring SSO via Microsoft Entra AD? What is the scope of the Email Listener Synchronization Service functionality?

Thank you in advance!
