' An Office365 OAuth2 access token must first be obtained prior
' to running this code.

' Getting the OAuth2 access token for the 1st time requires the O365 account owner's 
' interactive authorizaition via a web browser.  Afterwards, the access token
' can be repeatedly refreshed automatically.

' See the following examples for getting and refreshing an OAuth2 access token

' Get Office365 SMTP/IMAP/POP3 OAuth2 Access Token
' Refresh Office365 SMTP/IMAP/POP3 OAuth2 Access Token

' First get our previously obtained OAuth2 access token.
Dim jsonToken As New Chilkat.JsonObject
Dim success As Boolean = jsonToken.LoadFile("qa_data/tokens/office365.json")
If (success = False) Then
    Debug.WriteLine("Failed to open the office365 OAuth JSON file.")
    Exit Sub
End If


Dim imap As New Chilkat.Imap

imap.Ssl = True
imap.Port = 993

' Connect to the Office365 IMAP server.
success = imap.Connect("outlook.office365.com")
If (success <> True) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


' Use OAuth2 authentication.
imap.AuthMethod = "XOAUTH2"

' Login using our username (i.e. email address) and the access token for the password.
success = imap.Login("OFFICE365_EMAIL_ADDRESS",jsonToken.StringOf("access_token"))
If (success <> True) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


Debug.WriteLine("O365 OAuth authentication is successful.")

' 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 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 = "*"

Dim mboxes As Chilkat.Mailboxes = imap.ListMailboxes(refName,wildcardedMailbox)
If (imap.LastMethodSuccess = False) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


Dim i As Integer = 0
While i < mboxes.Count
    Debug.WriteLine(mboxes.GetName(i))
    i = i + 1
End While

' Sample output looks like this:
' Archive
' Calendar
' Calendar/Birthdays
' Calendar/United States holidays
' Contacts
' Conversation History
' Deleted Items
' Drafts
' INBOX
' INBOX/abc
' INBOX/misc
