Outlook MS 365


we just recently transition to Outlook MS 365 in our office
my main issue is that i cannot recreate my custom search folders from my Desktop to my app
i have tons of folders i use to filter my emails and i have folders within a folder

unfortunately, in the app - all unread emails go directly to their (rules) designated folder
this means, to check for any new emails - i have to scroll thru all my folders and see if there is a # besides it
at the same time, the # besides some folders within the folders cannot be displayed
