"Hello. My Outlook email account is completely unable to receive automated verification emails from the official sender ******@oracle.com.

I have already checked my Junk folder, Deleted Items, and Recoverable Items, but nothing is there. Furthermore, when I try to manually add this email to my 'Safe Senders' list in Outlook Web, the system throws a 'Cannot save changes' error.

It appears that Microsoft's backend mail servers are dropping or blocking incoming traffic from this Oracle domain due to a false positive. Could you please escalate this issue to your technical engineering team to unblock this sender/domain for my account?"

    Hello,

    Since the verification message does not appear in Junk, Deleted Items, or Recoverable Items, adding the sender to Safe Senders may not help if the message is being rejected before it reaches your mailbox.

    I recommend first asking Oracle to check their delivery logs for this verification email and confirm whether Microsoft accepted or rejected it. If possible, ask them for the SMTP response/error code, sending time, and Message-ID.

    If Oracle confirms that Microsoft accepted the message but it still never appears in your mailbox, please sign in to Outlook.com, select Help, describe the issue, then scroll down to Still need help? and select Yes. Include the sender address/domain, approximate sending time, and any SMTP information provided by Oracle.

    Regarding the “Cannot save changes” error in Safe Senders, you can also try adding only the domain:

    oracle.com

    Microsoft guidance:

    https://support.microsoft.com/en-us/outlook/safe-senders-in-outlook-com

    Best regards,

    No self-service escalation path to engineering is provided here.

    Supported actions are:

    1. In Outlook on the web, go to Settings > Mail > Junk email.
    2. Under Safe senders and domains, try Add safe sender, enter the Oracle sender address or domain, then select OK and Save.
    3. In the same Junk email settings page, review Blocked senders / Blocked domains and remove the sender or domain if it appears there.
    4. Check Rules and Forwarding in Outlook on the web to confirm nothing is moving, deleting, or redirecting the messages.
    5. If the sender is already on the safe list and mail still does not arrive, messages can still be blocked before they reach the mailbox because server-side junk filtering may stop them upstream.
    6. For Outlook.com support, use Help in Outlook.com, enter the issue, then scroll to Still need help? and select Yes. If sign-in is also affected, use the Outlook.com support entry point.

    Relevant limitation: adding a sender to Safe Senders does not guarantee delivery when the message is blocked before mailbox delivery.
