我有一个只有少数用户（比如说 10 个）的 LAN，他们想在云上查看他们的电子邮件。
我们正在使用 Active Directory 身份验证的 Windows 2008 R2 服务器上运行 Exchange 2010，所以我想我应该在 office365.com 上购买 Exchange Online 计划。但是我有一个关于 DNS 的问题，我们的服务器没有面向互联网的 IP，我应该如何处理这个问题，我应该购买 DynDNS 帐户吗？

Are you wanting to migrate your email to Office 365 and remove the internal exchange server?
If they just want to be able to access their email from a web browser then this is possible with Exchange 2010 already. You'll need an SSL Certificate to avoid certificate error messages accessing OWA. I would also contact your ISP about getting a static IP address. It shouldn't cost too much.
If you are migrating to Office 365 completely then you won't need a static IP but does take some planning and is very helpful to have someone on hand who has experience.

答案取决于您是要构建混合部署，还是只是将它们移至 office365 并放弃本地 Exchange 服务器。
如果您没有面向公众的 IP，我会说可以安全地假设您将交换服务器严格用作传入电子邮件的本地存储。我们一直看到（并修复）这种类型的设置。
office365 背后的想法是它可以在任何有互联网的地方访问，因此除非您想要混合部署，否则您不需要获取静态 IP 或动态 DNS 帐户来使用它。
