Exchange Server 2013/2016/2019 Security Updates May 2022

Hi All,

Yesterday at the Microsoft Patchday, the Exchange Server 2013/2016/2019 Security Updates May 2022 have been released.

• Released: May 2022 Exchange Server Security Updates

• Security Update For Exchange Server 2016 CU23 (KB5014261)

• Microsoft Exchange Server Elevation of Privilege Vulnerability

There is also a new format of the Security Update. The .exe File is a self-extracting, auto-elevating installer (.exe), which works best for manual installations.

• New Exchange Server Security Update and Hotfix Packaging

After the Setup is installed on all Servers you have to run “PrepareAllDomains” as an Enterprise Admin.

cd C:\Program Files\Microsoft\Exchange Server\V15\Bin
Setup.exe /IAcceptExchangeServerLicenseTerms\_DiagnosticDataON /PrepareAllDomains
