如何快速获取交换用户的SMTP地址? [英] How to get SMTP address for exchange user quickly?

问题描述

以下是我的代码，PrimarySmtpAddress使用50ms，需要15秒以上才能加载300个用户.我不熟悉Outlook API，似乎此属性是检索SMTP地址的常用方法，但是它太慢了.

The below is my code, the PrimarySmtpAddress use 50ms which need more than 15 s to load more 300 users. I am not familiar with Outlook API, and it seems this Property is the usual way to retrieve the SMTP address, but it is far too slow.

还有其他方法可以检索SMTP地址吗?还是我错误地使用了此属性?

Is there other way to retrieve the SMTP address or I use this property incorrectly?
