使用PHP-EWS发送电子邮件时获取ErrorNonexistMailbox

PHP-EWS版本：1.0.0-beta.2-PHP版本：5.5.9-Microsoft Exchange版本：2010

问题描述： 我试图使用php ews库发送一封连接到Exchange服务器的电子邮件，但收到一个不存在的邮箱错误。 要连接到Exchange服务器，我使用的帐户没有与之关联的默认邮箱。 在该服务器上，邮箱配置为可从我的帐户访问

例如

用于身份验证的Exchange帐户（域/用户）：测试/bob 服务器上配置的邮箱：alice@sample.com，bob没有任何与之关联的默认邮箱 鲍勃被允许进入alice@sample.com信箱

我怎样才能发送电子邮件alice@sample.com使用我的帐户（bob）而不获取不存在的邮箱错误
