Provide a 'By month' or 'Date Range' search to avoid hundreds of 'Load more' presses which takes forever to go back months.
Desktop Outlook let you effectively sort thousands of emails by either of name/date/Subject etc. 365 does not and my business has important emails that may go back a month, year or eighteen months plus!
With 365 you have to repeatedly hit 'Load More' to go back mere days, let alone months and a years worth of 'Load more' would take forever!
Provide a date range search that has no historic date limit or span and then a 'Sort By' option within that range once its loaded.
