You have a hybrid deployment of Exchange Server 2013 and Office 365. The mail flow
between Office 365 and the on-premises Exchange Server environment is routed through an
Exchange Server 2010 Edge Transport server. Your company is assigned a new set of
public IP addresses. A network administrator updates the external firewall address and all of
the associated DNS records. Office 365 users report that they cannot receive email
messages from on-premises users. You discover that outgoing email messages to Office
365 are in the Office 365 SMTP queue on an Edge server. You need to ensure that the onpremises users can send email messages successfully to the Office 365 users. Which tool
should you use?
A.
The Exchange Management Console
B.
The Exchange Control Panel in Office 365
C.
The Exchange Admin Center
D.
The Exchange Remote Connectivity Analyzer
