Security News > 2021 > March > Microsoft: Exchange updates can install without fixing vulnerabilities
Due to the critical nature of recently issued Microsoft Exchange security updates, admins need to know that the updates may have installation issues on servers where User Account Control is enabled.
Microsoft has added these warnings to all Exchange security updates released throughout the last few years.
Microsoft says that the installer will not display any errors or messages to let you know that the Exchange security updates have not been installed correctly.
Microsoft adds that the known issue would not occur if the Exchange Server security updates are installed through the Windows Update service.
The company also says that the Exchange services will be automatically restarted after applying the updates correctly.
Before updating your Microsoft Exchange servers, you will have to ensure that you've deployed a supported Cumulative Update and Update Rollup beforehand.
