I suspect that institutional knowledge about dealing with Exchange’s quirks is slowly going away as older employees move to other teams, companies, or retire, and are replaced with younger people who think they can solve everything using AI.
Microsoft’s been dealing with email for a very long time, starting with Microsoft Mail in 1988 then Exchange in 1996. Most of the newer features are just bolted on to the older systems. There’s plenty of legacy cruft in Exchange server (similar to how Windows 11 still has bits from Windows 95 and even icons from Windows 3.0 in it) and that’s the same codebase they still use for Microsoft 365 email.
