Am I crazy for wanting more than ever to fully embrace offline, privacy preserving technology? I'm okay with my Excel file on my HDD that I am in control over (and I've been spending time migrating away from the 'cloud' to a fully offline experience, where I can do anything I need without an internet connection, possibly for months at a time). This sounds like it ties you further into the MS ecosystem; it's likely you'll need an MS account and be willing to agree to their privacy policy to use this feature - hopefully there is an "opt out" at least if it's integrated into their applications. And I'm not seeing anything that says this can work if you disable your internet connection, which is crucial for many people. I also wonder about the longevity of these things. Imagine if an email was "alive" and could be "edited" after it was sent by anyone, like a 'module' as they're proposing. There's a value into having a static, in-time thing, like an email, that will contain the same content 50 years from when it was sent and isn't reliant on some database to get the content (and can be easily exported/imported at will). Dislike this. Moving everything to an online service sounds cool, except there are drawbacks to this approach.
