Using Classic Outlook on Windows for personal email, calendar, and contact management
I went back to the old version too, it's just ridiculous to not be able to save attachments. MS has been at this for what, nearly 40 years, and they keep making these dumb mistakes.
And as usual, I've probably spent 8 hours of time turning off all the "helpful" garbage and popups and autocompletes and whatever the heck Viva is.
