Visual C++ - Retrieve Email from Hotmail/Outlook/Office 365

The following c++ example codes demonstrate how to retrieve email from Hotmail/Outlook/Office 365 IMAP4 server.

Hotmail, Outlook.com, Live User

Hotmail/Outlook POP3 server address is pop3.live.com. It requires SSL connection on 995 port; Hotmail/Outlook IMAP4 server address is imap-mail.outlook.com. It requires SSL connection on 993 port;

You should use your Hotmail/Outlook email address as the user name for user authentication. For example: your email is liveid@hotmail.com, and then the user name should be liveid@hotmail.com.

Server Port SSL Protocol
pop3.live.com 995 SSL required Pop3
imap-mail.outlook.com 993 SSL required Imap4

Office 365

First of all, you should go to Office 365 Outlook -> Options -> See All Options -> Account -> My Account -> Settings for POP, IMAP, and SMTP access. You will get your Office 365 POP3/IMAP4 server address and port. The default POP3 server is outlook.office365.com on SSL 995 port; IMAP4 server is outlook.office365.com on SSL 993 port.

Server Port SSL Protocol
outlook.office365.com 995 SSL required Pop3
outlook.office365.com 993 SSL required Imap4
