Using Classic Outlook on Windows for personal email, calendar, and contact management
FINALLY!! Found Outlook for Windows Classic. Find the Microsoft Store on your pc; Search for Outlook for Windows (classic) Download and click to install, which takes quite a while. Go to Settings, Apps, Default Apps, Outlook. Set all file types to Outlook NOT Outlook new!! Return to Settings, Apps, Installed Apps and Uninstall Outlook New. And it works, doesn't try to revert to Outlook New - after months of struggling and complaining via Feedback about Outlook (new), some sanity has returned to my world...until 2029 anyway. Hope this works for you.
