    Hi @its_team1 ,

    When you are running with a hybrid environnement and you need to replace a certificate, the important thing are the connector created by HCW.
    Check this link, it can help : https://martinsblog.dk/exchange-replacing-certificate-for-microsoft-365-hybrid-connectors/

    For AAD Connect, no impacts with the Exchange SSL Certificate.

    Thanks

    Do you mean the certificate that is used for IIS will expire soon?

    About this certificate:

    1. you could click "Renew" to generate a renew request
    2. Then use this request to apply for a new certificate from a certification authority
    3. Import this new certificate to Exchange server to complete this new certificate request.
    4. Assign IIS service to this certificate, and run IISReset in CMD
    5. Rerun HCW.
