That's a very painful lesson in "the cloud is just someone else's computer" to a crowd that normally are exposed to ideas like "software and IT are not our core competency"
Which is why service level agreements were invented.
The idea is that it's someone else's computers that are managed more comprehensively than you could reasonably do yourself. But if you choose Microsoft to provide such a service for you, I don't know what to tell you.
When your system is down once a decade your boss yells and it’s your fault
When your outsourced system to Microsoft goes down every few months your boss can’t yell at you
Outsourcing is about shifting blame elsewhere
