Why can’t I collapse the folder structures?! – Microsoft Outlook Review

I was using the OWA app for ages which was great but has now gone out of support so now forced to use this app. Why on earth can’t I collapse my outlook folders? I have various folder structures in outlook with rules, I shouldn’t have to scroll through all the folders to get to where I need to be, especially when OWA had the collapse feature and THB was a much better app in terms of usability and logic
