Answer: 
Explanation:
Transport Control Protocol(TCP), User Datagram Protocol (UDP) ports, and Protocol Numbers are important to
TCP/IP networking, intranets, and the Internet. Ports and protocol numbers provide access to a host computer.
However, they also create a security hazard by allowing uninvited access. Therefore, knowing which port to
allow or disable increases a network’s security. If the wrong ports or protocol numbers are disabled on a
firewall, router, or proxy server as a security measure, essential services might become unavailable.
TCP port 25 is used for simple mail transfer protocol which is used to e-mail routing between mail servers.
TCP port 443 is used for Audio, video and application sharing sessions as well as data sharing sessions.
RTP/UDP port 50020-50039 must be used for outbound video sessions.
RTP/UDP port 50000-50019must be used for outbound audio sessions.

Configure a connector to send mail using Office 365 SMTP relay
This option is more difficult to implement than the others. Only choose this option when:
SMTP client submission (Option 1) is not compatible with your business needs or with your device
You can’t use direct send (Option 2) because you must send email to external recipients.
SMTP relay lets Office 365 relay emails on your behalf by using your public IP address (or a certificate) to authenticate Office 365. To do this, you’ll need to set up a connector for your Office 365 account, which is what makes this a more complicated configuration.
