Hello D2DCS,
Thank you for posting in the Microsoft Community! We're happy to help.
I understand that you have an issue configuring DKIM and DMARC.
Unfortunately, this is out of the scope of the Outlook Community since we don't have the required tool in the Community to check your account settings. Therefore you can
- Post your case in the Exchange Community Exchange - Microsoft Community Hub
- Or open a ticket in the Microsoft 365 Support. Our colleagues have the tools to further analyze the issue. Contact Microsoft Office Support - Microsoft Support
Thank you for your time and understanding. For other questions, feel free to add your post to the Microsoft Community.
Please do not hesitate to contact me with any questions or concerns. I look forward to hearing from you. Please understand that our initial response may not always resolve the issue immediately. However, with your help and more detailed information, we can work together to find a solution.
