The ImportCAChainaction is used to import the certificate chain from the certification authority (CA) that issued the certificate. In order for the validity of a certificate to be verified and for the certificate to be assigned or used by Office Communications Server in any way, the root CA certificate must be in Trusted Root Certification Authority. When you import the CA chain, you obtain all CA certificates in the certification path, including the root CA certificate. The ImportCAChainaction requires the following syntax.

Copy Code
LCSCmd.exe /Cert /Action:ImportCAChain /Filename:<file name>
[/L:<log file path>] [/XML[:{TRUE|FALSE}]]

Such as:

Copy Code
LcsCmd.exe /Cert /Action:ImportCAChain /Filename:Certfile.p7b
