Is it possible to install F-Secure Email and Server Security 12.12 on Windows Server 2019 Core with Exchange 2019?
Hello iicg, Tamas,
Exchange 2019 is not supported by current version (12.12).
Support will be added to the next Email and Server Security (ESS) release, but, please, note that initial Server Security 14.00 release, planned for Q2 2019, will not contain Anti-Virus for MS Exchange and SharePoint modules.
Full ESS 14 release is planned for H2 2019.
Please hold back the installation if your schedule allows, as the next-gen "F-Secure 14.00 for Servers" product is currently in beta version and may be released soon. (F-Secure 12.12 is quite old software by modern standards and may have performance issues.)
Otherwise, the F-Secure 12.12 release notes don't mention "Windows Core" limitations, but Exchange 2019 support isn't mentioned:
