I am not able to install E-Mail security because when trying to connect to the MSSQL database I get the following error (tranlated from geman):
 
The setup could not find an appropriate SQL-Provider ont the Host. SSL Security Error.
 
It does not matter if I use the inbuild SQL Express installer of F-secure or if I install another one.
 
The server runs W2019 and Exchange 2019.
 
How can I solve this?
