Platform SDK: Exchange 2000 Server

Setting Network Proxy Information

[This is preliminary documentation and subject to change.]

When using methods such as IMessage.AddAttachment and IMessage.CreateMHTMLBody, you may need to access network resources through a proxy server. You set up the proxy configuration for a Message object as follows:

Set the http://schemas.microsoft.com/cdo/configuration/urlproxyserver field in the Configuration object's IConfiguration.Fields collection.
Optionally set the http://schemas.microsoft.com/cdo/configuration/urlproxybypass field to the value "<local>". With this setting, the proxy service will be bypassed for local addresses.
Optionally set the http://schemas.microsoft.com/cdo/configuration/urngetlatestversion field to force retrieval of resources directly and bypass the cache.
