Using New Outlook on Windows for personal email, calendar, and contact management
Just in case anyone is interested - Microsoft certainly is not - I have moved all my correspondence over to Gmail and attached my gmail account to my Legacy Classic Outlook - a very simple procedure via "Add account." If you don't have a Legacy Classic Outlook remaining on your device, I am informed that there are free downloads available.
As far as I can see, this is the only way of maintaining your sanity. Yes, it's a nuisance advising everyone of a new email address, but I can say in my case it is worth it! One or two things in gmail are annoying, but can be worked around, and Google has a good spam filter. And so far I have been able to use all of the Classic Outlook functions as I always could.
Shortly I will be deleting my New Outlook account for ever, and never coming back. It is the biggest load of software rubbish ever produced. It's not worth Microsoft even tinkering with it, it is so bad.
