Overview
Reinstate is an action that can be applied only on the suspended certificate. Suspend is a temporary revocation of a certificate where the user is unsure about certificate usage. Once reinstated, the certificate will get resumed to serve its purpose normally. The suspend and reinstate are the actions supported only by a few CAs such as Microsoft, Entrust, and so on.
Note:
This option is available only for Microsoft and EJBCA certificate authorities.
