Can't see the shared group inbox
In the old web outlook I could switch between Personal and Group Mailbox.
No such option exists in the new one.
Sorry for the inconvenience. We currently don’t have support for Group mailboxes. You will only be able to see the mails for Groups that you follow in your inbox. To see the Group mailbox you can use the Outlook app available on the iOS and Android store.

I wanna see shared mailboxes and shared calendars too.
Those with the name 'New Outlook' do anything bad.
