# 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"
# }

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

# Login
# Use the email address of the Yahoo Mail account that granted authorization.
$success = $imap.Login("user@yahoo.com",$accessToken)

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

$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:
$wildcardedMailbox = "*"

$mboxes = $imap.ListMailboxes($refName,$wildcardedMailbox)
if ($imap.LastMethodSuccess -eq $false) {
    $($imap.LastErrorText)
    exit
}

$i = 0
while ($i -lt $mboxes.Count) {
    $($mboxes.GetName($i))
    $i = $i + 1
}

# Sample output looks like this:

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