My email does not have the toggle option in the top right corner to get the classic outlook back. There is no longer the old outlook in the store either. I have also tried the steps in registry editor and that didn’t work out either.

Can I just click 'uninstall' on the New Outlook icon?
See my response, just above. You need to uninstall the new and re-install the old.
I don't think the registry key changes did anything.
In trying to get back to the old Mail, I tried editing the registry per your instructions. Got down in the registry to Outlook but there was no subgroup "Preferences". What do I do now?

Everyone in my office has had a problem with the new Outlook: errors displaying new mail, excessive CPU usage and memory consumption (large percentages of these) - you all have problems and that's why you're here.
Uninstall the "new" outlook.
Then download the new one (it will say it's an "offfice download" but it's just Outlook:

FWIW, I also did do the regedit of the keys provided in the first few pages of this thread; I even created the path that it indicated should be there (as well as added the flag to the path that seemed to be there.)
Good luck!
