Even the user side of Microsoft's email is confusing and prone to loosing emails. O365 defaults or at least the recommended settings will just quarantine emails without notifying anyone. I guess Microsoft doesn't trust users to not open emails in the spam folder? I think I have it configured now to alert the recipient and me on quarantined emails but there are at least two relevant dashboard (Exchange and umm Security Center? who knows what the current names are today) that probably have like 35 submenus and 1000+ settings. Running my own email server would be easier. Another thing, a few months ago I noticed a couple incoming emails were not quarantined/blocked but also not delivered. I don't think the issue has reoccurred since but it's just crazy that emails are just lost sometimes.
