Sending, receiving, and organizing email in Outlook.com
Hi
Since emails are still arriving in the Junk folder, your Hotmail mailbox is receiving mail. The issue is more likely related to Outlook.com’s junk filtering or a mail rule rather than a delivery failure.
Please first open Junk Email, select a legitimate message, then choose Report > Not junk. Also go to Settings > Mail > Junk email, check the Blocked senders and domains list, remove any legitimate addresses/domains, and add important senders to Safe senders. Microsoft’s instructions are here: https://support.microsoft.com/en-us/outlook/mail/block-or-unblock-senders-in-outlook
Then check Settings > Mail > Rules and temporarily disable any rules that move or delete incoming messages: https://support.microsoft.com/en-us/outlook/mail/manage-email-messages-by-using-rules-in-outlook
After that, send a test email to the Hotmail address from another account.
