Probably not because it would need to be an off-the-peg solution with support included for my bosses to even begin to consider it. But I have heard of Collabora and I know it’s decent.
More in the running would be a cloud solution from the amazing Framasoft, including Framapad
None of this is to disparage LibreOffice, which apparently offers value to many people and that’s great.
Seconded. Been a user for years without a single problem.
PS: There’s also Proton and Posteo, they’re all fine. The important bit is to pay for it. This is a critical hub for your personal data. It’s completely aberrant that people have allowed themselves to be trained to accept a free service in exchange for spying. A dollar or two a month is not prohibitive for anyone. We should all be paying for this service.
