  • Hi,

    What certificate error did you get? Could you provide a screenshot of the error so that we can further look into it?

    In addition, may I know what is the certificate used for? Are you using it to encrypt emails?

    Have you tried adding the certificate to the Trusted Root Certification Authorities store and then see if this issue continues? For your convenience:


    Hope this helps.
