Not receiving emails related to multi factor auth codes from a specific sender (company)

Question

For more than 24h now I do not receive emails related to multi factor auth codes from a specific sender (company). I receive other emails normally, and have checked all the technical suggestions in your help/FAQ page like blocked sender list, etc. The company in question says its not an issue on their side.

Hello Goke

Thank you for reaching out to Microsoft Q&A Forum. I understand how disruptive this is to not receive emails related to verification codes from a specific sender.

Just to confirm, have you already tried the steps mentioned in the Q&A Assist reply under your post? If yes, did you encounter any difficulties with those steps?

In the meantime, please try the additional steps below:

1. Double-check on Outlook on the web

• Sign in to Outlook on the web
• Double-check all folders (Inbox, Junk Email, Deleted Items, Archive), ensure your inbox filter is set to All (not "Unread", "Flagged", etc.)
• Check Focused / Other tab (if Focused Inbox is enabled), emails may land in Other. You can also temporarily turn Focused Inbox off to test.
• Go to Settings > Mail > Junk email:
  • Under Blocked senders and domains: Confirm the website’s reset sender or their domain is not listed
  • Under Safe senders and domains: Add the exact sender address (if known), and/or add the domain
  • Select Save

2. Search for hidden emails:

Use the Outlook's search box and try to search for:

• the company domain
• “code”, “verification”, “OTP”, “token”

3. Check Inbox rules

In Outlook on the web's settings, check for malicious rules/forwarding:

• Go to Settings > Mail > Rules/ Sweep: delete any suspicious rules you did not create (especially rules that moves/deletes mail)
• Settings > Mail > Forwarding: make sure nothing is forwarding.

4. Create a rule for the sender/domain

If you know the sender’s domain/address, create an Inbox rule like:

• Still in Outlook web, go to Settings > Mail > Rules > Add new rule
• Condition: From contains the exact domain/ address
• Action: Move to Inbox
• Enable “Stop processing more rules”

5. Check your internet connection

• Make sure your device has a stable internet connection and try switching networks (e.g., from Wi-Fi to mobile hotspot) then test again.
• Request the code from a different browser/device or from an incognito/private browser window

Answer 2

If you are not receiving emails related to multi-factor authentication codes from a specific sender, here are some troubleshooting steps you can take:

1. Check Spam or Junk Folder: Sometimes, emails can be filtered into your spam or junk folder. Make sure to check these folders to see if the emails have been misclassified.
2. Email Server and Mailbox Settings: Ensure that your email server and mailbox are configured to accept emails from the sender. Verify that the sender's email address is not blocked.
3. Inbox Rules: Check if there are any inbox rules set up that might be moving or deleting emails from that specific sender. Sometimes, rules can inadvertently affect email delivery.
4. Email Security Settings: If you have an email security appliance or software (like Barracuda or Cisco), check its settings to ensure that it is not blocking or quarantining emails from the sender.
5. Sender's IP Address: If the sender's IP address has been flagged for suspicious activity, it might be throttled or blocked by your email provider. You can check with your IT department or email provider for more information on this.
6. Contact IT Support: If you have checked all the above and still do not receive the emails, consider reaching out to your IT support team for further assistance. They may be able to provide more specific insights based on your organization's email configuration.

By following these steps, you should be able to identify the issue affecting the delivery of your multi-factor authentication emails.
