On the live.com website or the browser version of Outlook, this feature doesn't exist. This is such an important feature to have. No one knows how many emails they have in total and therefore it removes the incentive to clean your inbox. Is it not beneficial to Microsoft to have less emails stored instead of more? Makes no sense for Microsoft to remove this. Every email competitor has this basic feature. When you can see the total email count (Read and Unread emails) and you see that there's too many emails stored, you know it's time to clean your inbox. I've been waiting for this feature for years now.
