            {
                try
                {
                    var protocolLogger = new ProtocolLogger("imap-log.txt");
                    using (var client = new ImapClient(protocolLogger))
                    {
                        await client.ConnectAsync("outlook.office365.com", 993, SecureSocketOptions.SslOnConnect);
                                                //mail look like this  [email protected]
                        await client.AuthenticateAsync(new SaslMechanismOAuth2(settings.ClientLogin, result.AccessToken));


                        var a = client.Inbox.Open(FolderAccess.ReadWrite);
                        await client.DisconnectAsync(true);
                    }

                }
                catch (Exception ex)
                {

                }
            }

S: A00000003 BAD User is authenticated but not connected.

This means that authentication worked, but you haven't gone into your account settings and enabled IMAP access.
