You have a legacy application that needs to send email to employees.
The legacy application runs on a client computer that must send email by using SMTP through Exchange
Online.
You need to identify the correct host name and port information.
Which settings should you use?
A.
Outlook.office36S.com and port 25
B.
Outlook-Office365.com and port 587
C.
Smtp.office365.corn and port 587
D.
smtp.office365.com and port 25
C maybe? https://support.office.com/es-es/article/Configuraci%25C3%25B3n-de-POP-e-IMAP-en-Outlook-para-Office-365-para-empresas-7fc677eb-2491-4cbc-8153-8e7113525f6c?ui=es-ES&rs=es-ES&ad=ES

Answer C is correct indeed, not B. Incoming (IMAP and POP) is outlook.office365.com, outgoing is smtp.office365.com. And of course port 587 for secure SMTP.

C is the right answer, reference : https://support.office.com/en-us/article/Office-365-URLs-and-IP-address-ranges-8548a211-3fe7-47cb-abb1-355ea5aa88a2?ui=en-US&rs=en-US&ad=US#bkmk_exo

It is a LEGACY application and it sends email ONLY to employees = INTERNAL. That would point to the “D”.
I vote for the answer “D”.
Expl. – using port 25 to smtp.office365.com and without any authentication you can send emails freely to any user in your organization. All emails outside the organization will be blocked.

D does not even exist. Port 25 is not open on office.com
it´s C

Not that Microsoft links are always correct as they never seem to update everything with all the changes they make but indeed port 587 is the recommended port. Being a legacy application it might want to use port 15? it does not specify.
According to this link you can use port 25 though.

I vote for D here, MS is refering to legacy application and for that port 25 its used

Answer D
Legacy = No TLS 1.0+ support. Many old applications and multi-function devices (even some not so old printer/scanners) don’t allow you to specify a port or support TLS encryption.
Microsoft supports this via Direct Send, which only allows port 25 and TLS is optional. For internal use only as specified see Option 2:

From reading the questions the requirements are must use SMTP and send only to employees. According to the documentation ‘Direct Send’ should be utilized which will send email only to users inside the organization and utilize port 25. Therefore I believe ‘D’ is the correct answer.
Below is the URL from which I base my conclusion:

I’m incline to think D (smtp, port 25) too. Yet when I did a “telnet smtp.office365.com 25” from my home pc (Windows 10) and I couldn’t make a connection whereas “telnet smtp|outlook.office365.com 587” connects instantly with the greeting below
220 DM5PR2201CA0066.outlook.office365.com Microsoft ESMTP MAIL Service ready at Sun, 15 Oct 2017 05:35:09 +0000
So I vote for C

It is “C”;
Outgoing server (SMTP): 465 or 587
