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,, Live User

Hotmail/Outlook POP3 server address is It requires SSL connection on 995 port; Hotmail/Outlook IMAP4 server address is 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, and then the user name should be

Server Port SSL Protocol 995 SSL required Pop3 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 on SSL 995 port; IMAP4 server is on SSL 993 port.

Server Port SSL Protocol 995 SSL required Pop3 993 SSL required Imap4


Before you can use the following sample codes, you should download the EAGetMail Installer and install it on your machine at first. Full sample projects are included in this installer.

Add Reference

To use EAGetMail POP3 & IMAP4 ActiveX Object in your project, the first step is “Add header files of EAGetMail to your project”. Please go to C:\Program Files\EAGetMail\Samples_VS2008\pop3_imap4_simple.vcNative or C:\Program Files (x86)\EAGetMail\Samples_VS2008\pop3_imap4_simple.vcNative folder, find eagetmailobj.tlh and eagetmailobj.tli, and then copy these files to your project folder. You can start to use it to retrieve email and parse email in your project.
