Microsoft released Cumulative Update 15 (CU15, KB5042461) for Exchange Server 2019 on February 10, 2025 – and it's the FINAL major CU before end of support on October 14, 2025! This update is a full installation that includes all previous security fixes, bug resolutions, and new features to keep your on-premises email secure and running smoothly. In this comprehensive tutorial, I'll walk you through: Prerequisites & Prep: Check your current build, run the Health Checker, and ensure no Exchange 2013 servers remain (CU15 blocks coexistence!) Download & Install: Grab the 5.9GB package from Microsoft Download Center and step-by-step installation via GUI or PowerShell (including /PrepareAD and schema updates). Key Fixes & Features: Auto-cleanup of old OWA files to free disk space (KB5047359). Edge Transport service stability improvements. Extended Protection enabled by default for better security. Support for Windows Server 2025, TLS 1.3, and new product keys. Common Issues & Troubleshooting: Fixes for queue viewer errors, Outlook password prompts, and DAG maintenance mode. Plus, tips for hybrid setups and testing in a lab first. Post-Update Best Practices: Verify build number (15.02.1748.010), restart services, and plan your upgrade to Exchange Server Subscription Edition (SE) for ongoing support. Why Update Now? With Exchange 2019 reaching EOS soon, CU15 is your baseline for testing SE RTM (releasing Q3 2025) – no feature changes between them! Skipping this could leave you vulnerable to known issues.
