Using Classic Outlook on Windows for personal email, calendar, and contact management
Not disagreeing with what you are stating. However, having the functionality of seeing total number of emails in a folder doesn't really apply to folders 10 years old for those of us that use that functionality for workforce. It applies to working folders of today. I do not keep emails in my inbox. For personal and professional I have a folder called IMMEDIATE. that is a folder that I know I need to look at all of the emails in and either reply or do something. I want to see the total of the emails in that folder to know if there is still something that need to be done, not just ones that haven't been marked as read. Following that is an ASAP. Not as important as the IMMEDIATE but also emails that I need to review and do something with. Once again want to see the total in that folder not just the number of unread. All other emails have been filed in there respective folders and to you point don't care at all how many are in those. So it comes down to having working folders and knowing how many total are in those folders that you need to process ("how many are in the folder left that I need to process?"). Having that view capability without having to go into the folder itself.
I recieve hundreds of emails daily both personally and professionally. Having that quick view capability of knowing how many emails I still need to process is instrumental. Not having it completely upsets that workflow, as I now have to click on all of the respective folders to see if they have emails that need processing manually. And still can't see how many are in there.
Different people use different methodologies for there workflow. For those of us that use that quick view capability to see how many total emails are in a folder, removing this feature is terrible.
