This indicates whether the client intends to write the wrapped stream interface that is returned.
This indicates whether the decompressed RTF is supposed to be written to the stream that is pointed to by the lpCompressedRTFStream pointer of the WrapCompressedRTFStreamEx function.
This indicates whether the decompressed stream is also converted to the native body before returning the stream.
This flag cannot be combined with the MAPI_MODIFY flag.
This is the code page value of the message. Typically, this value is obtained from the PidTagInternetCodepage Canonical Property on the message. This value is only used when the MAPI_NATIVE_BODY flag is passed in ulFlags. Otherwise, this value is ignored.
This is the code page value of the returned decompressed stream that you want. If this is set to a non-zero value, the WrapCompressedRTFStreamEx function converts the stream to the specified code page. If this is set to a zero value, MAPI decides which code page to use. This value is used only when the MAPI_NATIVE_BODY flag is passed in ulFlags, and the body format is not RTF. Otherwise, this value is ignored.
