All the emails i am sending goes to receiver's junk folder

Hello,

We have verified that SPF, DKIM, DMARC, and ARC are all passing correctly for our domain sustelements.com (please see authentication results in the message header). Despite all checks passing, our emails from Remove for privacy still go to Junk for Outlook/Exchange recipients, while Gmail delivers correctly.

Could you please review our domain and IP reputation in your system and whitelist or adjust the filter to ensure legitimate delivery?

Hi @abdulaziz alsulamai,

Thank you for posting your question in the Microsoft Q&A forum.
Please understand that our forum is a public platform, and we will modify your question to cover your organization domain name in the description. Please notice to hide these personal or organization information next time you post error or some information to protect personal data.

Regarding that your email is direct to the recipient Junk mail box. I’d like to ask a few quick questions to better understand the situation and assist you more effectively:

Is the recipient part of another organization or in same organization?
Does this happen with all recipients with same domain or only with specific ones?
Has the recipient checked if they have any inbox rules that might be redirecting your emails to the Junk folder? You can guide them to check by going to: Settings > Mail > Rules
Can you ask the recipient to check if their organization has any mail flow rules that might be affecting email delivery? You can refer to this article for more details:Mail flow rules (transport rules) in Exchange Online | Microsoft Learn

In the meantime could you ask that recipient to add your email account to the Safe Senders List in Outlook on the web

Select Settings > Mail > Junk email.
Under Junk email, scroll down to Senders, and select the Safe senders and domains tab.
Select + Add safe sender, and enter the email address for the recipient you want to add.
Select OK, and then select Save.

Or you could refer to this article: Add recipients to the Safe Senders List in Outlook - Microsoft Support

Thank you again for your time and understanding. While my initial response may not resolve the issue immediately, I’d like to gather more details about your situation so I can assist you more effectively.

I really appreciate your patience, and I’m here to help. Looking forward to your response!

Hello Dear,

Thank you for your detailed response.

I appreciate your guidance, but the steps you’ve provided (such as asking recipients to check inbox or mail flow rules) are not practical in my situation. These recipients are external clients, and I don’t have access to their internal email settings.

The issue I’m facing is that emails sent from my domain are consistently being delivered to recipients’ Junk folders, even though: (for same domain and other organisation)

SPF, DKIM, and DMARC are correctly configured and verified as valid (checked via Red Sift and MXToolbox).

The domain uses GoDaddy nameservers.

The issue occurs across multiple external recipients and organizations.

Could you please investigate further from the Microsoft side to identify if there’s any reputation or filtering reason causing Microsoft’s system to mark our emails as spam?

I’d appreciate your help in analyzing any header or reputation-related factors that might be leading to this issue, and guidance on improving deliverability from our side.

Thank you for your time and assistance — I look forward to your update.

Hi @abdulaziz alsulamai,

Thank you for your reply, and I truly appreciate your effort in trying to resolve this issue.

May I ask: have you been sending the same email content multiple times?

If so, I recommend sending that same email to your own personal email account, then checking the message header of that email. This can help us understand how the message is being processed and whether it's being flagged as spam.

Please share the message header with me via private message, as it may contain sensitive information.

You can refer to this article for guidance: View internet message headers in Outlook - Microsoft Support

Alternatively, you can check the message header yourself to see the SCL (Spam Confidence Level) and BCL (Bulk Complaint Level) values. These indicators help determine whether your message is being treated as spam.

You could refer to these article: Spam confidence level - Microsoft Defender for Office 365 | Microsoft Learn

Bulk complaint level values - Microsoft Defender for Office 365 | Microsoft Learn

If the SCL and BCL level is not high I strongly recommend you to open for a support request. Microsoft’s support team will need to step in. A technical support engineer can perform a remote session to investigate the situation, verify the backend configurations, and run any necessary synchronization tools to resolve the problem. If the issue requires further attention, they can escalate it to a specialized team for deeper analysis.

The Global Admin should create a service request with Microsoft support to get advanced technical assistance and diagnostics. For detailed instructions on how to get support, please refer to Get support - Microsoft 365 admin.   

If you’re unsure who the Global Admin is within your organization, you can find guidance on locating them here: How do I find my Microsoft 365 admin? - Microsoft Support.  
Thank you for your patience and understanding. We appreciate your continued trust.
