Download/Retrieve Email from Hotmail/Outlook/Live/Office 365 in Delphi

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 Delphi.

Introduction

Hotmail/Outlook POP3 server address is outlook.office365.com. It requires SSL connection on 995 port; Hotmail/Outlook IMAP4 server address is outlook.office365.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
outlook.office365.com 995 SSL required Pop3
outlook.office365.com 993 SSL required Imap4

App Password with Microsoft Account

If your account enabled two-factor authentication, you cannot login your account by normal user authentication, you should create an App Passwords and use this App Password instead of the user password.

Another solution is using OAUH, please see Hotmail IMAP OAUTH section.

Note

Remarks: All of examples in this section are based on first section: A simple Delphi 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.

Hotmail IMAP OAUTH

Microsoft Live SMTP servers (Hotmail, Oultook personal account) have been extended to support authorization via the industry-standard OAuth 2.0 protocol. Using OAUTH protocol, user can do authentication by Microsoft Web OAuth instead of inputting user and password directly in application.

Microsoft will disable traditional user authentication in the future, switching to Microsoft OAuth (Modern Authentication) is strongly recommended now.

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.

Important

Office 365 has started to disable user login in POP/IMAP protocol, you should use Office365 POP/IMAP/EWS OAUTH instead of traditional user/password login.

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

App Password and Office 365 OAUTH

If your account enabled two-factor authentication, you cannot login your account by normal user authentication, you should create an App Passwords and use this App Password instead of the user password.

Office 365 has started to disable user login in POP/IMAP protocol, if basic authentication has been disabled in your tenant, you have to use Office365 POP/IMAP/EWS OAUTH.

TLS 1.2

TLS is the successor of SSL, more and more Email servers require TLS 1.2 encryption now.

If your operating system is Windows XP/Vista/Windows 7/Windows 2003/2008/2008 R2/2012/2012 R2, and you got connection error with SSL/TLS connection, you need to enable TLS 1.2 protocol in your operating system like this:

Enable TLS 1.2 on Windows XP/Vista/7/10/Windows 2008/2008 R2/2012
