关于OWA中的密送(BCC)选项

介绍一下使用Exchange OWA来写邮件时的密送(BCC)选项：

在Exchange 2000的OWA中，没有密送(BCC)选项；
在Exchange 2003的OWA中，密送(BCC)选项默认就是显示出来的；
Exchange 2007 的OWA中，每次要使用密送(BCC)，都必须在选项中勾选“显示密件抄送”，必须每次要使用时都进行显示操作。

如果想让Exchang 2007的OWA中默认显示密件抄送，可以尝试以下方法，出自http://groups.google.com/group/microsoft.public.exchange.misc/browse_thread/thread/c275aa0aacd6eb61?pli=1：

This worked for us. Alter this file at your own risk. You can apply
this fix without restarting any services and it works on the fly.

******In \Exchange2007\ClientAccess\Owa\forms\premium
\editmessage.aspx*********
******Change this Block of code (search for bcc)**********
<tr id=”trBcc” <%= ShowBcc ? “” : ” style=\”display:none\”" %>>
<td>
<a id=”btnBcc”r” : “l”%>”
<%RenderOnClick(“shwABM(\”divBcc\”);”);%> hidefocus=”true”
tabindex=”-1″ href=”#”>
<img align=absmiddle src=”<

ThemeFileId.AddressBook);%>”> <
%=LocalizedStrings.GetHtmlEncoded(Strings.IDs.BccEllipsis)%>
</a>
</td>
<td>
<%
if (ShowBcc)
RecipientWell.Render(Response.Output, UserContext,
RecipientWellType.Bcc);
else
RecipientWell.Render(Response.Output, UserContext,
RecipientWellType.Bcc, RecipientWell.RenderFlags.Hidden);
%>
</td>
</tr>
******To This************
<tr id=”trBcc”>

<a id=”btnBcc”r” : “l”%>”
<%RenderOnClick(“shwABM(\”divBcc\”);”);%> hidefocus=”true”

**************************
Now BCC is on by default and can be turned off in options.
