alt Hacker NewsMy locally installed ms office 2019 also works 365d/y.
My softmaker office suite also.
Anyway, I do admit I mostly use libreoffice nowadays, except for 1) communication with customers, and 2) a few excels libre can't handle.
I still have to find a good alternative for (local installed) outlook, I'm trying out thunderbird, but I'm not sure it would be able to replace outlook. I still have to try whether it can handle a 50gb imap inbox, and besides lacks a few essential features.
May I ask what features you consider essential are lacking in Thunderbird? I'm not a heavy e-mail user (for now, hopefully ever), and Thunderbird seems very feature-packed to me.
The only thing I'm afraid about is Thunderbird wiping one's inbox [^1] [^2] (both by the same user with discussion underneath)
