I have the exact opposite experience. We're running an older version of Office (2016?) at work with Windows 7. Thse are supported by MS via the extended support contracts. It will be upgraded shortly. Basically I get blue screens, rendering issues, slowness, freezing, crashing, random glitches. I regularly lose emails. The changes to Outlook are abysmal too. When a meeting invite I've accepted is amended (e.g. a 'Starting in 5 minutes email or update'), the calendar invite is no longer accepted so the reminder doesn't pop up. Whomever decided that un-accepted invites shouldn't pop up, has caused so much upset, tears and hate. I would describe my windows machine as entirely useless. It has got so bad that I use my iPhone to respond to emails and to use the calendar features. I've been considering learning some .NET to write a pop up app that is always on top so that when there's a meeting it shows up. Has anyone done that? It seems pretty basic.
