Using classic Outlook for Windows in business environments
Ultimately, as Microsoft products continue to deteriorate compared to the heady days of Windows 7 and Office 2010, it seems easier to give up and switch to Open Source products such as Thunderbird. Not ideal, but better than suffering the lack of functionality of "New Outlook". Also means all your emails are not being copied to MS (for whatever purpose! Unless of course you are using MS email - outlook.com, hotmail in various guises, live, etc.) Again, lots of non-MS services available.
