// 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.

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

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:
string wildcardedMailbox = "*";
