But… they do all the time. Almost everybody uses some mix of Office, Slack, Notion, random email providers, random “security” solutions etc. The exception is the opposite. The only thing prevents info leaking is ToS, and there are options for that even with LLMs. Nothing changed regarding that.

In my personal experience, it's very common for big companies to host email, messengers, conferencing software on their own servers.

In my experience it’s very common for big companies to not host. Think Fortune 500 type companies. Most are legally happy with their MSA and reasonably confident in security standards.

Mind sharing a clarification on your understanding of "common" and "big"?

[ruszki]

Yes, then they use Outlook for example. Have you checked the ToS of the new Outlook version for commoners? They flat out state that they can use all of your emails for whatever they want.

Also, companies host for example an Exchange server on prem; and guess, what it connects to? Why you can usually access account at outlook.com?

[consonaut]

Your on premise exchange server has zero connections to outlook.com. OWA (Outlook Web Access) looks similar to outlook.com but has otherwise nothing to do with it.

Then let’s call outlook.office.com, and that’s an OWA, and you’re redirected there if you login on outlook.com. And that’s the exception when on prem Exchange servers really work as more than mere proxies nowadays. I’m quite sure that there are still real fully on prem solutions, but it’s laughable these opinions, that most company really care about this. They simply don’t.

All of those things are hosted on-prem in the bigger orgs I have worked in.

I don't think Slack or Notion have on-prem/self-hosted options.
