basic authentication certificate for active sync

I have correctly configured ActiveSync certificate-based authentication, however, when I tested it on my iPhone mobile device, I encountered these error logs on the server (server exchange 2010) :

Hi Sound S, My name is David and I'd love to help. I understand your frustration and will do my best to resolve this issue. Here is a solution to the issue you are facing. If the customer is using Intune to manage the device, advise them to create a new configuration policy for an iOS Trusted Root Certificate that points to the Intermediate Certificate Authorities' *. CER file. Then, advise them to open the company portal on the device and refresh the policy. The connection should now succeed. Detailed guidance on this can be found in the following Microsoft community article: https://learn.microsoft.com/en-us/microsoft-365/troubleshoot/authentication/certificate-based-authentication-fails-on-ios I hope this helps.
