We have a server that needs to send notifications when an action occurs. How might I create this M365/AAD user so that it's hidden from the domain and isn't included on any distribution lists or org-wide groups, etc.?
Any security tips on how to protect this not-monitored account?
EDIT: I ended up adding the user to another domain (email@example.com), hiding them from GAL (option right at the top of Exchange Admin), and, more importantly, I found the Group membership option to remove users from a Group so they don't receive org-wide emails. Everything right within the setup at the Exchange Admin site.
