Hotspot Question
You have a hybrid Exchange Server 2016 organization.
Users use Outlook on the web. All mailboxes currently reside on-premises. You have an internal
public key infrastructure (PKI) that uses a certification authority (CA) named CA1. Certificates are
issued to users to sign and encrypted email messages. You move a mailbox to Exchange Online
and you discover that the mailbox fails to exchange signed or encrypted email messages from the
on-premises mailbox users. You need to ensure that all of the mailboxes that were moved to
Exchange Online can send encrypted email messages to the on-premises mailboxes. The
mailboxes must also be able to receive encrypted email messages from the on-premises mailboxes.
You export the required certificates to a file named Export.sst. What command should you run next?
