Using Classic Outlook on Windows for personal email, calendar, and contact management
There are only a few folders that Microsoft adds to outlook. I think the problem most people are referring to on this thread is when they create their own folder structure, which can get quite large if you are trying to organize everything that comes through your inbox. I probably have a couple hundred folders that have accumulated over the last decade. For those folders that you create yourself, the new outlook can screw up the organization, which makes it impossible to find a folder that is no longer sorted alphabetically. The fix I referred to relates to putting your own custom folders back in alphabetical order.
If you change the name of the folder that's in the wrong spot alphabetically (such as by putting a "z" in front of the name), it will move the folder to the correct spot (the end of the list in my "z" example).
It doesn't works for one simple reason: the program doesn't lets you change the name for the default folders: let's say I want to move the "Drafts" folder way down to the bottom, according to your suggestion, I'd have to rename it to something like "Z Drafts", am I right?, but turns out, the damn "New" Outlook won't even let me change that folder's name.
