It depends if the company has a sufficient size to support a production,
mission critical email service. How many engineers to you need to ensure a
proper support rotation? I work mainly in the SME space and haven't seen
self hosted email in over 5 years.

I will admit that the screech of the cloud brigade is often loud and
incoherent but you have to choose your battles. Email is a bitch. It seems,
from a techie point of view, the problem with Microsoft is that they are
forcing an all or nothing approach. If you take Office365 then you must
take the Azure Exchange also which means the core infra guys are pretty
much left high and dry, reduced to helping people install adobe acrobat on
the new Windows10.

I empathise. I've worked as an infrastructure admin and "Devops" engineer
for over 10 years and now my role has been automated away by Kubernetes.
Change is hard.
