    Hi,

    Backing up Exchange 2016 Mailbox (Classic) goes into pending state. Entry in log file:

    Exchange auto discover for CAS server for XXX failed with error [The request was aborted: Could not create SSL/TLS secure channel.]
    Error in getting the Exchange Server settings, failing the backup.

    Anyone happened to see this specific error before / knows a solution?

    Thanks.

    Can you perform a manual discovery and then run a job - does this work?

    Check if the Certificate used on the Exchange 2016 servers are SHA1

    Thanks all. Configuring a Proxy server for MB backup in combination with the MapiHttpDisabled reg key solved the issue.
