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.

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.
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?
