Possible Causes:

Troubleshooting:

但我不知道如何检查我的exchange已经安装了多少种字体, 如何安装新的字库文件比如"GB18030"
谢谢大侠指教一下.

这个问题应该不是exchange 字体影响的，检查一下，发件人的发送邮件的邮件格式。

格式一般用UTF8，或者自动就好

试试检查一下下图的设定：

我也遇到了这个问题，怎么也解决不了

Here is something out of Exchange tester's toolbox:
Before testing or using GB18030, you must configure your client and server as below for correct display of GB18030 characters.
Client machine
Set the system locale to Chinese
1)      Go to Control Panels -> Regional and Language Settings -> Languages and make sure support for East Asian fonts is checked
2)      Go to the advanced tab and make sure that the language is set to "Chinese (PRC)"
Download and install the GB18030 patch from
       http://www.microsoft.com/downloads/release.asp?releaseid=32385
Change the font and language of acceptance options in IE to support GB18030
1)      Run IE 6.0; navigate to Tools and then Internet Options to open the "Internet Options" dialog.
2)      Click the Languages button to open the "Languages" dialog box
3)      Click the Add button to open the "Add Languages" dialog box
4)      Find and Add the language named "Chinese (China) [zh-cn]"
5)      Click the Ok button until you are back to the "Internet Options" dialog box

Change the encoding options in IE to display GB18030 characters
1)      From IE, navigate to View->Encoding and check that Chinese Simplified (GB18030) is the current encoding option.  This may have to be done every time a file with GB content is opened from within IE.  
Server
Download and install the GB18030 patch from http://www.microsoft.com/downloads/release.asp?releaseid=32385 . Please note here that if the Global Catalog Server is running Windows 2000, you need to install the patch on it too.

To send a message encoded in GB18030

To send a GB18030 message with OWA
1)      Log in to OWA and open a new message window
2)      Right click on the gray area of the window and from the drop down menu make sure that GB18030 encoding is selected
