For many services there are drop-in Replacements available. I don't see what's so special about Mail or Calendar from Microsoft vs other vendors.

The Quality is also Shit. I get some stupid Errors when trying to Access OWA every other day. Then I have to reset cookies/cache and can login again

Yes and they keep blocking features in Firefox on Linux. When I change the user agent to match edge on windows things suddenly work fine.

When it's set to Firefox attachment uploads don't work and ever morning it jumps to "please wait while we're signing you out..." when i never asked for that. When it thinks it's edge it just stays signed in.

Not to mention the huge amount of telemetry I need to block with ublock origin.

You don't want a drop-in replacement for each service, you want one for the entire system.

Microsofts advantage is ActiveDirectory integration. Centrally managed users and machines, every user, every application, every service authentications through the AD.

Organizations opt for Teams all the time, because it's part of the package and fully integrated. There's no reason they couldn't pick something else, but why deal with it when Teams just work (sort of).

		Is there a combination of open standards to drop in to replace AD integration with self management? OAuth enabled systems aren’t enough, central management of users and machines are huge. If that core matures, it opens up the market for replacements in other areas. Teams, Outlook and the Office Suite need first grade replacements.
