Body: Hi everyone,
I've noticed a few people asking where to find a "fixed" or updated download for Exchange Server 2016 64-bit. It is a common misconception that you have to download the base RTM version and then manually apply years of patches.
Here is the best practice for 2024:
Microsoft releases each Cumulative Update (CU) as a complete refresh of the product. You do not need to install previous CUs.
Hope this helps anyone spinning up a new lab or migration!
As of 2026, Exchange Server 2016 Mainstream Support has ended, but Extended Support continues until October 14, 2025 for most editions (check your specific SKU). Some volume license agreements extend further.
That means security updates are still released—but only for the fixed new ISO base (CU23). If you hold onto an ancient ISO, you will be unable to apply these patches.
