手机邮箱设置无法成功

手机邮箱设置数量超过10个后无法在新的手机上设置新的邮箱了，如何处理？

下面是微软的回复：

You have 10 phone partnerships out of the maximum allowed 10 partnerships. After you reach the maximum, you can't create additional partnerships until you delete existing ones from your account. To do so, sign in to Outlook Web App, click Options > Phone > Mobile Phones, and delete any unused partnerships.
