Hi Tinsley Li,
Welcome to Microsoft Q&A forum.
I understand how concerning this is, especially when you can receive AIMA “contact form” messages but not the “default” emails generated by the AIMA portal.
One quick clarification to narrow this down: what is the exact “From” address or domain shown for the missing AIMA portal email (please redact any personal details), and do you receive any bounce or “delivery failed” message?
Since different message types are often sent from different sender addresses/systems, the first step is to confirm whether the portal emails are being filtered, moved, or not delivered to your mailbox at all.
- Check whether the email is being filtered or sorted: In Outlook.com, please check Junk Email and also the Other tab (if Focused Inbox is enabled). Then set your Inbox filter to All (not Unread) and sort by Date to ensure the message is not hidden by a view/filter.
- Check Rules and Forwarding: Go to Settings, then Mail, then Rules and confirm there is no rule that moves or deletes messages from AIMA. Also check Mail, then Forwarding to ensure mail is not being redirected.
- If the message never appears anywhere: If you are not receiving a specific email and nothing shows up in any folder, Microsoft’s guidance is to contact the sender and have them follow Sender Support for Outlook.com delivery investigation.
If you still need help after the checks above, you can contact Outlook.com Support from within Outlook.com: sign in, select Help on the top menu, search for your issue, then scroll down to Still need help and submit a support request.
Thanks for your time, and I’ll be glad to help further once you share that detail.
