Classic Outlook - Until when will it be supported & available for use?

I think a better question is: "When will Microsoft fix all the bugs and return the beloved classic features and functions to 'New' (and useless) Outlook?"

Deep within MS site is an install executable for classic outlook. I would post the link but I forgot to save it (kicking myself). I discovered this by googling the issue and a site unrelated to Microsoft had the link. Perhaps you can find it that way?

Neither the stock market nor Microsoft give a fat finger about any of us.

You are actually suggesting the typical Outlook user go in to the registry and change a setting?

Otherwise, thanks for the details. Oddly windows 11 removed the icon I set up yesterday for classic outlook after I rebooted.

I have only tried using New Outlook for 2 days. I couldn't bear it for more.

1. It changed all the times in the calendar to one hour BEFORE the time they are set in Classic.
2. I could find no way to sort the "Sent" folder to the "To:" field which I use a lot.
3. Even though MS says it is possible to switch back and forth, it is not. When I toggle the "new" setting off, a feedback form appears; I fill it out; click "submit", Outlook closes down and does NOT reappear in Classic form. If I reopen Outlook, it is still as "New". Same thing if I DON'T fill out the form. In fact once one has reinstalled MS 365, it takes an act of congress to find and install Classic.
4. Even though I have my OWN MS365 license, apparently there is no way to get MS to use MY license instead of my organization's so I can't set up a group distribution list. It forces me to use the outlook.com address for the organization. Did someone think a person would NEVER have access to two MS365 licenses? and, further, use one license for one purpose and the other for something else?

Please tell me that Microsoft didn't hand this app to the local high school to develop. How did they let this thing out the door?
