VB6 - Retrieve email from Yahoo account¶

The following vb6 example codes demonstrate how to retrieve email from Yahoo IMAP4 server.

Yahoo POP3 server address is pop.mail.yahoo.com. It requires SSL connection on 995 port; Yahoo IMAP4 server address is imap.mail.yahoo.com . It requires SSL connection on 993 port. You should use your Yahoo email address as the user name for user authentication. For example: your email is myid@yahoo.com, and then the user name should be myid@yahoo.com.

Server	Port	SSL	Protocol
pop.mail.yahoo.com	995	SSL required	Pop3
imap.mail.yahoo.com	993	SSL required	Imap4

Installation¶

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 reference of EAGetMail to your project. Please go to menu -> Project -> References -> and select EAGetMailObj ActiveX Object, click OK, the reference will be added to your project, and you can start to use it to retrieve email and parse email in your project.

Add reference in VBA (EXCEL/Access/Outlook)¶

Open VBA IDE by press Alt+F11, Please select menu -> Tools -> References -> and select EASendMailObj ActiveX Object, click OK, the reference will be added to current VBA project, and you can start to use it to retrieve email and parse email in your VBA project.

To better demonstrate how to retrieve email and parse email, let’s create a VB 6.0 Standard EXE project at first, then add a CommandButton on the Form, double-click this button. It is like this

VB6 - Retrieve email from Yahoo account - example¶

The following example codes demonstrate how to download emails from Yahoo account using IMAP4 protocol. In order to run it correctly, please change email server, user, password, folder, file name value to yours.

Note

To get full sample projects, please download and install EAGetMail on your machine.

App Password¶

If you got authentication error, you need to enable Allowing less secure apps in your Yahoo account. Or you can generate an App Passwords and use this app password instead of your user password.

Although Yahoo supports OAUTH, but it doesn’t provide mail permission, so OAUTH is not a solution for Yahoo mail.

VB6 - Retrieve unread/new email from Yahoo account - example¶

Because IMAP/EWS/WebDAV support read mail flag, with this feature, we can also retrieve unread/new email only from Yahoo like this

TLS 1.2 protocol¶

TLS is the successor of SSL, more and more SMTP 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, 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

32bit/x64 ActiveX DLL¶

Seperate builds of run-time dll for 32 and x64 platform

File	Platform
