我有一种情况，我想连接到一个电子邮件服务器，其唯一公开的邮件/日历服务是 Activesync（它是一个 Exchange 服务器）。唯一暴露的网络界面是可怕的“OWA light”。
我想找出一种方法来同步来自此 Exchange 的邮件，以便它出现在桌面邮件客户端（或 webmail 客户端，如果有任何以这种方式工作的话 - gmail 不支持订阅的 activesync - 它发布它的邮件为activesync，这不是我想要的）。
基本上我想要的 ascii 艺术是：
Exchange => Activesync <=> 客户端应用程序
有很多移动客户端应用程序可以做到这一点，但我正在寻找可以作为订阅者处理 activesync 的桌面或 webmail 客户端（IMAP 的工作方式）。
感谢您提供任何参考或想法！

Ok - of course 20 seconds after posting this, I find an answer on superuser. Probably where I should have posted to begin with (I swear I googled before posting but apparently not enough).

Answer: http://davmail.sourceforge.net/
This appears to be a POP3/IMAP and SMTP bridge to activesync which is exactly what I want. If it works as claimed, I can point any mail client to it and it will sync my mail in two directions so I can send messages that will pass through the system and see all the messages that come in.
Update 2013: I've been using this DavMail OSS software for a few years now and it's really great. For retrieving mail from relatively locked-down Exchange servers, that only permit OWA access, it very easily allows me to "break out" of the box the IT guys want to put me in, and use rational tools and protocols like IMAP, POP, SMTP and Thunderbird to send/retrieve mail from the Exchange server. If I were really motivated, I could get this running on a public server, and serve my mail so that Gmail could poll it, and bridge Exchange and Gmail, but of course I'd have to pay more attention to security.
I haven't had a ton of luck getting the Calendar portions of the system working, primarily because I can't find a caldav client (on Windows) that I like - I think the DavMail part works as well as can be expected.
我今天尝试了“TouchDown”。我可以将我的电子邮件和日历等从我的企业 ActiveSync 帐户提取到我的 Mac。
您使用的是哪个操作系统？它们支持各种操作系统，包括 Windows 8.1 和 Mac。
