Summary
Resolving Microsoft email delays due to IP reputation and recipient interaction requires a comprehensive approach that addresses both technical and engagement-related factors. Key strategies include monitoring IP reputation through tools like SNDS and JMRP, improving email engagement by segmenting users and providing relevant content, implementing strong email authentication (SPF, DKIM, DMARC), maintaining a clean email list, enrolling in and monitoring feedback loops, optimizing email content to avoid spam triggers, and gradually warming up IP addresses. Understanding Microsoft's specific requirements and actively participating in their programs are also crucial for identifying and resolving deliverability issues.
Key findings

Expert view
Expert from Email Geeks explains that the problem is not sending speed but recipient interaction. Microsoft believes users don't want the mail. Fixing this will resolve the rate limiting. Sending to active users aims to change the ISP’s opinion, assuming positive interaction improves filter behavior. However, Microsoft now follows links, creating false activity. She questions the segmentation, particularly regarding '[internal]' failures, and suggests investigating why the ESP suppressed those addresses.
