You have an Exchange Server 2013 organization.
You purchase a Microsoft Office 365 subscription and configure a hybrid deployment.
The network contains an SMTP relay server named smarthost.contoso.com. The server is configured to use a certificate that has a subject name of smarthost.contoso.com.
All users have Microsoft Outlook 2013 installed on their client computer. Outlook 2013 is configured to connect to mail.contoso.com.
All Exchange servers have a certificate that has a subject name of mail.contoso.com.
You discover that email messages sent from on-premises users are not delivered to Office 365 recipients. You discover that the Send connector for Office 365 uses a smart host of smarthost.contoso.com.
You need to ensure that the on-premises users can send email messages to the Office 365 recipients.

A. Run the Hybrid Configuration Wizard again.
B. Configure the Microsoft Exchange Online Protection (EOP) Send connector to use smarthost.contoso.com
C. Configure the centralized mail transport option.

E. Assign a certificate that has a subject name of smarthost.contoso.com to the Send connector.
