February 2023 Exchange Server Security Updates

Microsoft Exchange Servers security updates have been released for February 2023.

These updates are available for the following specific versions of Exchange Server:

Exchange Server 2013 CU23 SU20 (Microsoft Exchange Server 2013 will reach its end of support on April 11, 2023)
Exchange Server 2016 CU23 SU6
Exchange Server 2019 CU11 SU10 & CU12 SU6

The recommendation is to install these updates immediately to protect your environment.
In the scenario where you do a Cumulative Update(CU), you need to make security updates. Otherwise, remember that you have to do the Cumulative Update(CU) first and then the Security Update(SU).

Inventory your Exchange Servers to determine which updates –> “Exchange Server Health Checker
Choose your current CU and your target CU to get directions –>  “Exchange Update Wizard
If you encounter errors during or after installation of Exchange Server –> “Exchange Setup Assist


Note: Don't double-click the 'MSP file' to run it. Run Command Prompt (not Powershell) as an Administrator.


Have a nice day!
