    IIS server delivers an old, expired SSL Certificate, giving ERR_CERT_AUTHORITY_INVALID


    I enabled IIS on one of my machines Win 10, made a tiny website, bought an SSL Cert SECTIGO, not self-signed, installed it. All went OK. When I test the website in IIS or from any other machine or browser, it gives this error: ERR_CERT_AUTHORITY_INVALID. If I click the error, it shows that the SSL certificate for the website is not the one I bought and installed, but an old one that expired over 2 years ago. I don't know where it's coming from, and it's not one I ever added or bought.The website is in the ddnsfree.com domain from dynu.com, the certificate was purchased from dynu.com for th

    SSL certificates for email

    My SSL certificate for email on my 2012 r2 exchange server expired. I went to GoDaddy and installed the new valid certificate but now I have both the old expired cert and the new valid cert. Now when I try to create a new email account and migrate it to
    365 from my on-premise server (hybrid environment) it errors and says the certificate is invalid.

    Can I remove the expired certificate? Or is there a different way for the exchange console to recognize the new valid cert instead of the old expired one?

    I just don't want there to be issues if I remove the old certificate.

    IIS server delivers an old, expired SSL Certificate, giving ERR_CERT_AUTHORITY_INVALID

    Windows mobile use expired root certificate

    Hello David,

    The situation is like that:

    1. The CA used to issue SSL cert to exchange server are expired soon.

    2. The CA is renewed with a new CA root cert.

    3. A new SSL cert is issued to exchange server and is installed to IIS.

    4. The new CA root cert. is added to windows mobile device trusted root cert store.

    5. When windows mobile device remote sync to exchange server, the mobile device report that the server certificate is expired.

    The problem can be fixed by deleting the old expired CA root cert. I think the mobile device should use the new cert instead of reporting the old cert is expired. In other situation such as Internet explorer, the browser will use the current CA root cert instead
    of the expired one.

    Just want to know this is normal or a fault.

    Thanks.
