What should you do?

Your on-premises network contains a proxy server and a firewall. The proxy server is configured to inspect the contents of HTTP and HTTPS sessions to identify disallowed content. Only the proxy server can connect to the internet through the firewall.

You implement Microsoft Exchange Online.

Users report that they receive an error message when they attempt to connect to their mailbox by using Microsoft Outlook.

From the internal network, you connect to https://outlookoffice.com/mail and discover a certificate error.

You discover that the certificate error contains information about a certificate issued by your company’s internal certification authority (CA).

You need to ensure that all the users can connect successfully to their mailbox.

What should you do?
A . Install a new root CA certificate on the client computer of each user.
B . Configure client computers to bypass the proxy server when they access https://*.microsoft.com.
C . Disable HTTPS content inspection on the proxy server.
D . Install a new root CA certificate on the proxy server.
