Download/Retrieve Email from Hotmail/Outlook/Live/Office 365 in C#

In previous section, I introduced how to download email from Yahoo account. In this section, I will introduce how to download email from Hotmail/MSN Live/Outlook.com/Office 365 account in C#.

Introduction

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

Note

Remarks: All of examples in this section are based on first section: A simple C# project. To compile and run the following example codes successfully, please click here to learn how to create the test project and add reference to your project.

Retrieve Email from 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

[C# Example - Retrieve emails from Office 365 account using IMAP4]

The following example codes demonstrate how to download email from Offic 365 account using IMAP4 protocol.
