Please pardon my ignorance, I do not have access to a Microsoft®
system and thus cannot really verify my assumptions: Let us say for a
year or so, I receive answers to my own enquiries by mail, especially
when they come from organisms « abroad » (outside France), that are injected by a server at “outlook.com”, although the sender has a
complete infrastructure and mail-servers at her/his/its disposal.
Am I right to assume that outlook.com in this cases is something
integrated in their communication policy, rather by convenience than
by necessity, and part of some bigger software-monster which just
does it that way as mail is not the operator's main concern.
There were “systems” like this in my time, but I am not up to date on what is custom, today. It is only boring to receive badly written
messages of presumably unknown origin and then have to reconstruct a
context that might explain the references to something that I am
really involved with.
Do the domains have SPF?
Is the MS server listed in the SPF?
I have not checked, but I can try for two of the companies concerned.
Give me a little time, as I have to find, read about and understand
the tools.., again.

Yes, it is common these days for organizations large and small to outsource essential services like email to cloud providers like Google, Amazon, Microsoft, and many others. Spammer and other malicious actors also love this practice, because it allows them to use legitimate customers of those services as human shields for their abuse. For that reason, I largely block cloud providers.
Without any specific messages/headers, it is not possible to say if the messages you’re receiving are spam or not, but the certainly sound unwanted.
The best technique I have found to deal with email abuse is: <https://en.wikipedia.org/wiki/Disposable_email_address>
They are not SPAM and not even unwanted, as most are reactions to my own enquiries, be it belated. What unnerves me is that I contact an organisation, then get responses via unpredictable services.
I do not need a disposable address. Bayesian filters here, on the server of my
hosting association and my IP-filters are sufficient for the time. It is also possible that I just do not attract so much SPAM. This thread is about something else, anyway.
