Sending, receiving, and organizing email in Outlook.com

not receiving auto generated emails, but regular emails are coming through ok
I am sorry, but this a common and on-going problem, because Microsoft has put in place some very stringent Anti-Phishing policies.
If the sending domain fails any of the "Impersonation" test (DMARC, SPF and DKIM) then the email is bounced. i.e. Sender gets a Non-Delivery Report (NDR) and the email never gets to your mailbox. Not even Junk.
See https://learn.microsoft.com/en-us/defender-office-365/anti-phishing-policies-about
If you can get the full domain for the provider's email notification service (almost never the same as the domain of the website you visit or where "normal" emails come from) then you can check the Anti-Phishing configuration yourself using a Domain Checker. A search for Sendmarc Tools should get you a hit for a well know one.
But you are not alone, just a sample of recent similar reports:
