What are the most common causes of Microsoft 365 performance issues?

While most providers blame Microsoft's cloud for performance problems, our diagnostic data shows that 82% of Microsoft 365 performance issues stem from local configuration or network problems. Our performance optimization service uses our comprehensive assessment framework to identify the real culprits, from suboptimal DNS configurations and proxy interference to network congestion and client-side resource limitations. We then implement our military-grade optimization protocol that includes targeted network configuration changes, TCP optimization, and our proprietary caching framework – delivering consistent performance improvements of 30-50% for applications like Teams, SharePoint, and OneDrive. This systematic approach has resolved performance issues for organizations ranging from 20 to 5,000 users.
