Outlook keeps blocking certain mails

Question

Certain mails from specific senders are filtered and blocked by my outlook account. They don't even appear in the junk folder, they just don't arrive to my account, no matter what I do. I've added rules to send them to the inbox, I've added those addresses to safe senders list... still doesn't work.

Hi again,

Great to hear you found it! Yes, selecting "Outlook" instead of "Outlook.com" often reveals more support paths it's an easy detail to miss.

Hi again,

Thanks for your follow-up!

To contact Microsoft support directly regarding blocked or missing emails:

1. Go to support.microsoft.com
2. Sign in with your Outlook account.
3. Scroll down and click “Contact Support” (it may show as “Get help” or a virtual agent at first).
4. Choose Outlook.com > Emails are missing > then select Contact a support agent when the option appears.

Explain that legitimate emails are not reaching your mailbox, even though you’ve taken steps like adding to the Safe Senders list. Mention that the senders have working SPF/DKIM/DMARC and that you suspect silent filtering. This should help escalate your concern to someone who can look deeper into Microsoft’s backend filtering.

Hi there,

I’m Cherrelyn, and I’m here to help.

If emails from specific senders aren’t arriving in your Outlook account even after adding them to your Safe Senders list and setting up rules it's possible that Microsoft's filtering system is blocking them before they reach your mailbox. This can happen if the sender’s domain is flagged or misconfigured. I suggest asking the sender to check their email server's SPF, DKIM, and DMARC settings to ensure their messages are properly authenticated. Meanwhile, you can also check your blocked senders list and contact Microsoft support to investigate if their filters are silently dropping the emails.

I hope this will help and if you have any question please don't hesitate to reply to this thread.

Warm regards,
