Outlook Office 365 grouping emails with minimise and maximise capability

Hi there, not sure if I'm in the right place to post this as first-time user.  In previous versions of Outlook, there was capability to group emails by an attribute i.e. From, Date etc and minimise or maximise visibility of the grouped emails.  I cannot find anything like this in Outlook Office 365 webmail.  This was incredibly handy for productivity.  Is there anything like this in Outlook 365 as the only thing I can find it to sort by sender.
