What is the best way to integrate SharePoint Team Calendar and Outlook meetings using Office 365 E3?

Since this post seems outdated, I’m going to ask a related question:

I understand that Office 365 doesn’t support SharePoint online with email enabled list/library due to compliance/performance reason. That said, what is the best way to create a team calendar in SharePoint that integrates the meeting invites from outlook along with the team holidays, events, etc combined as one calendar that is easy to access?

Another approach I was thinking was- is it possible to ‘overlay’ a SharePoint site team calendar with “site mailbox” driven calendar but I don’t see that site mailbox has a calendar ‘tied’ to it.

I’m hoping that there’s a recommended direction we can take to address this.

Thanks,

Samir
