How to Turn OFF 'Unverified Sender' Block on individual emails - or fully!!

Do your job and reply for the past 2.5 pages.

Hi Everyone,

I have worked out the solution for adding a sender to a "Safe Sender" list when you are using the email server and not the app.

This will prevent a sender being flagged as "Unverified" whenever you get sent an email from them.

1. Open up the server using your browser and find the "settings" icon in the top right corner.
2. Under settings select page select "junk email".
3. Under junk email scroll down to "Safe senders and domains".
4. Under Safe senders and domains add your safe sender or domain name and press "Ok" to save the address.

I cannot vouch for this method in the app as I do not use it, but definitely works when using a browser.

Please comment below if you find this works or not.

Thanks

Peter

Please see my detailed response to the poster. The MSFT person did get a bit too technical in their response - but the Unverified warning is their to protect people from potentially spoofed email from malicious actors. The SENDER needs to correct the issue, not the recipient.

What you're describing is not related to the Unverified issue the person who created this post was talking about.
If you have an IT department, you may want to contact them.
Otherwise, you should probably create a separate post to see if anyone can shed light on what you're talking about.

I'm not aware of anything that would require forwarding of email to only forward emails from your safe senders.

I'd see if your IT department has implemented some sort of new policy that is causing this restriction.

Hi Lisa,

Thank you for connecting with us in Microsoft community.

Before moving forward, could you please allow me to collect below information from your side to narrow down the situation?

According to your description for "Unverified Sender"

The warning message you are seeing in Outlook about an "Unverified sender" is a security feature designed to protect users from potential phishing or spoofing attempts. This warning is triggered when the sender's email address cannot be verified through authentication mechanisms like SPF, DKIM, or DMARC.

You may need to refer this detailed official document to get understanding: Email authentication in Microsoft 365 - Microsoft Defender for Office 365 | Microsoft Learn

While it may be frustrating to see this warning for legitimate senders, it is important to prioritize email security and caution when interacting with emails that may pose a risk. The "Delete" option is provided as a precautionary measure to prevent users from engaging with potentially harmful emails.

If you believe that a sender flagged as "unverified" is legitimate, you can try to check the following steps:

2. Contact your IT administrator: If you are part of an organization and if you are an End user, you may need to reach out Office 365 global admin or IT department in your organization to review the email authentication settings and potentially whitelist the sender's domain.

Furthermore, if you are still facing this situation after performing above steps, your certain part of scenario should be diagnosed by Microsoft's backend side support team by collecting some more advanced logs information from Office 365 global admin person via remote session. Frontline technical support engineer can also involve specific support team for further investigation about some particular situation if it is required. After diagnosing the scenario, our technical support team can provide possible information from their end.

If there are any known issues, this information can be provided by the technical support engineer from their backend resources.

Since we forum moderators have limited permissions and access resources, due to this reason, we are unable to connect Microsoft frontline support team from this public community for further diagnosis.

For the above provided standard process information, in your organization, Office 365 global admin person may need to contact Office 365 support team on backend  via an open service request so they can diagnose this specific scenario through some more technical resources,

For this standard process, here's the official document for the global admin reference: Get support - Microsoft 365 admin | Microsoft Learn****(Online Option).

Note: End-user person may need to contact the Office 365 global admin person in your business organization for connecting with technical support engineer for further process.

Important note: If any organization's Office 365 Business/Business/Education subscription is from a syndicated partner or reseller, and if the global admin can't open the service request on their end, they may need to contact the reseller's support provider so they can help the global admin to open the service request on their end. after the Office 365 support team will involve in the created service request.

I hope I have provided all the required process information and direction for your current situation.

Your cooperation precious time is highly appreciated.

Sincerely

Vaidya Darpan
