See more Yahoo Mail Examples

List Yahoo Mail mailboxes.

Chilkat ActiveX Downloads

ActiveX for 32-bit and 64-bit Windows

' This example assumes the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

' See Get Yahoo Mail OAuth2 Access Token for Desktop App 
' for sample code showing how to obtain a Yahoo Mail access token.

' In this example, our access token was previously saved to the following file which contains JSON like this:
' {
'   "access_token": "kCVQdnOdul...LHucA--",
'   "refresh_token": "AIenVXETSo0jklFBVkPS8vVm8E.Ej9ToRG.xDbDYmZ65WIs5t6CZhDrD",
'   "expires_in": 3600,
'   "token_type": "bearer",
'   "xoauth_yahoo_guid": "HGDQCVF5JB4YDOWHITQJFBHCWA"
' }

Dim json As New ChilkatJsonObject
Dim success As Long
success = json.LoadFile("qa_data/tokens/yahooMail.json")
If (success <> 1) Then
    Debug.Print "Failed to load GMail access token file."
    Exit Sub
End If

Dim accessToken As String
accessToken = json.StringOf("access_token")

' Do OAuth2 authentication by using the access token as the password in the Login method below...
Dim imap As New ChilkatImap

imap.Ssl = 1
imap.Port = 993

' Connect to the Yahoo IMAP server.
success = imap.Connect("imap.mail.yahoo.com")
If (success <> 1) Then
    Debug.Print imap.LastErrorText
    Exit Sub
End If

' Indicate that XOAUTH2 authentication is to be used:
imap.AuthMethod = "XOAUTH2"

' Login
' Use the email address of the GMail account that granted authorization.
success = imap.Login("user@yahoo.com",accessToken)
If (success <> 1) Then
    Debug.Print imap.LastErrorText
Else
    Debug.Print "Successfully authenticated with Yahoo IMAP using XOAUTH2!"
End If

' The ListMailboxes method returns a Mailboxes object
' that contains the collection of mailboxes.
' It accepts two arguments: a refName and a wildcardedMailbox.

Dim refName As String
refName = ""
' refName is usually set to an empty string.
' A non-empty reference name argument is the name of a mailbox or a level of
' mailbox hierarchy, and indicates the context in which the mailbox
' name is interpreted.

' Select all mailboxes matching this pattern:
Dim wildcardedMailbox As String
wildcardedMailbox = "*"

Dim mboxes As Mailboxes
Set mboxes = imap.ListMailboxes(refName,wildcardedMailbox)
If (imap.LastMethodSuccess = 0) Then
    Debug.Print imap.LastErrorText
    Exit Sub
End If

Dim i As Long
i = 0
Do While i < mboxes.Count
    Debug.Print mboxes.GetName(i)
    i = i + 1
Loop

' Sample output looks like this:

' Archive
' Bulk Mail
' Draft
' Inbox
' Inbox/emailsWithAttach
' Inbox/test
' Sent
' Trash

' Disconnect from the IMAP server.
success = imap.Disconnect()
