A reliable, corporate-friendly, with advanced support model alternative of Exchange + AD is something that could sink a titan like Microsoft in 2 decades, at least its non-cloud business (but then for cloud alone they are just one of many, nothing special there).

Literally everybody is fu*king fed up with M$ arrogance. But you can't get rid of Active Directory and Exchange. Make comparable alternative (with say 80% of most used use cases, no need to die on some corner case hill) and many many corporations will come.

This won't come from some startup, it has to be a company like Mozilla.

Are you sure of that? There have been alternatives to Microsoft Office for decades. Yet most businesses use and pay for Microsoft Office, even though their employees most likely don't need anything that doesn't exist in those alternatives.

Why would it be different with email?

Nobody got fired for buying ~~IBM~~ Microsoft. People trust Mozilla though, they've built their brand on not sucking as bad as M$ and Google

I don't think you understand what I was writing about - none of that is MS Office. Thats another topic, but without this (and say some sort of domain propagation rules) bigger corporations will never move out of MS.

My understanding is that you say "someone could make an alternative to X and that would kill Microsoft because everybody hates Microsoft".

My answer is "there have been examples of alternatives to Microsoft products for decades, and it hasn't killed Microsoft at all, so I don't see why it would be different for another service (in your case, email)".

Did I misunderstand your point?

Ooh, imagine if they also threw in some kind of Teams alternative, maybe based on XMPP or Matrix! That might get a lot of attention.
