Agree that the latest Outlook update is a disaster. I was fortunate when going through the process of installing it and ran into problems that I aborted the process and did a bit of research. That's when I learned that the new Outlook is not yet compatible with a POP3 account, although there is no mention of it in the installation process. At that point the Outlook Classic was still on my computers, but no longer the default email program. At that point i was able to uninstall the New Outlook and revert to Classic.
I am probably a bit of a Luddite, but I want my emails on my own system and not on some distant corporate server. I'll deal with synchronizing my various computers and devices.
MS is becoming more intrusive in forcing people to adopt a subscription model. The last update completely scrambled how File Explorer appears on one of my desktops, requiring about a half hour to get it back to where it was usable again. At present I'm struggling to keep an older laptop and desktop, that are working fine now, to work until I'll probably have to replace them next October when Win 10 Pro security support ends.
At that point I'll wonder if there will even be a standalone Office program or just a subscription model.
