Process when Microsoft Office 365 Calendar Integration in Interviews is enabled?

Dear All,

1. I would like to know how is the interview scheduling supposed to work differently upon enabling Microsoft Office 365 Calendar Integration in Interviews?
2. When we schedule/create an interview for a candidate (along with enabling Teams integration) in Oracle fusion , is it supposed to automatically create a calendar appointment in Outlook (since the Microsoft Office 365 Calendar Integration in Interviews along with Teams integration is enabled? Is there a automatic sync? If not, please let me know how the system is supposed to work post enabling the calendar integration as it is not so clear from the Oracle Documentation.
3. Is it required to create each Recruiter user manually in Azure? If yes, please share the steps on where and how the same is supposed to be done?
