Header file:

MAPI spooler

HRESULT RemovePreprocessInfo(
  LPMESSAGE lpMessage


[in] Pointer to the preprocessed message from which information is to be removed.


Preprocessed information was removed successfully.

The MAPI spooler calls a function based on RemovePreprocessInfo. A transport provider registers the RemovePreprocessInfo based function at the same time it registers the parallel PreprocessMessage based function in a call to the IMAPISupport::RegisterPreprocessor method.

An image rendering suitable for fax transmission is an example of preprocessed information written by a function defined by the PreprocessMessagefunction prototype. The MAPI spooler usually calls a RemovePreprocessInfo function after sending a message that contains preprocessed information.
