    Hi @debbie carvalho

    I’m sorry to hear that you are still unable to receive emails from this specific contact after trying the suggested troubleshooting steps. I understand how inconvenient this can be, especially when other emails are arriving normally.

    At this point, the issue may need to be checked directly by the Outlook.com Support team. Please follow these steps to request live-chat assistance:

    • Go to Contact Microsoft Support.
    • Select Show expanded list of products.
    • Select Outlook > Get Home support.
    • Enter Outlook live chat, then select Get Help > Contact Support.
    • Use the affected Microsoft account. If you cannot access it, use another Microsoft account to view the available support options.
    • In the Support Assistant, type Talk to a live chat agent, then select Contact Support.
    • Under Products & Services, select Other Products > Outlook, then choose Chat with a support agent in your web browser.

    Please note that this is a user-to-user support forum. Moderators, contributors including external Microsoft employees cannot directly intervene in Microsoft product features or access back-end systems. Our role is limited to providing technical guidance on reported issues, requests, or ideas only.

    I hope the Support team can help investigate this issue further.

    Being on the Safe Senders list does not guarantee delivery in every case.

    Common reasons this can happen:

    1. The message is being blocked before it reaches the mailbox Outlook.com can reject mail during the initial delivery check. If that happens, Safe Senders will not help because the message never reaches Junk Email or Inbox. This is especially relevant when the sender’s domain fails authentication checks or has sender-side delivery problems.
    2. The sender needs to fix their mail system If the sender receives a non-delivery report or rejection, the issue is usually on the sender side. The sender should check the delivery log, SMTP response, and any rejection details from Microsoft.
    3. The message may be in another folder or affected by mailbox settings Check Junk Email, Deleted Items, Archive, and Other if Focused Inbox is enabled. Also check Settings > Mail > Rules and confirm the sender or domain is not in Blocked senders and domains.
    4. Safe Senders only prevents junk filtering after delivery reaches the mailbox Messages from addresses or domains on the safe senders list are not moved to Junk Email, but server-side filtering can still block messages before delivery.
    5. Junk list limits can interfere Exchange junk email lists have a cumulative default limit of 510 KB across Safe Senders, Blocked Senders, and Safe Recipients. Also, if Trust email from my contacts is enabled and there are many contacts, that can contribute to exceeding the limit.

    What to do:

    1. In Outlook.com, search for the sender’s address across All folders.
    2. Check Settings > Mail > Rules for any rule moving or deleting mail.
    3. Check Settings > Mail > Junk email and confirm the sender is not also listed under blocked senders.
    4. Ask the sender to send a test message and check whether they receive a bounce or rejection notice.
    5. If they do, the sender or their mail administrator must review their sending configuration and authentication.
    6. If needed, add the sender’s full address or domain again under Settings > Mail > Junk email > Safe senders and domains, then select OK and Save.

    If the sender’s mail is being rejected before delivery, the fix is on the sender side, not in the Safe Senders list.
