Limitations of Outlook 365 on Mac - shared calendars and mail boxes

I cant find a single definitive resource on using Outlook 365 on a Mac.

Have a small number of users in an office who use a mixture of a Mac and Windows. 365 and Outlook will work well for the windows users but need more confidence it will work well for Mac users as we grow.

With outlook installed on a Mac is it possible to:

1. View diary conflicts when scheduling meetings for other exchange users
2. View other users calendars
3. Access a shared calendar
4. Access a shared mail box

I imagine there are limitations around these using OWA etc but need to understand how they perform using the right clients
