Writing applications for Microsoft® Exchange in C is quite similar to doing so in C++. The various header files required are the same as those required with C++. These headers are generated by the MIDL.exe tool, which automatically builds special C functions that simplify working with the interface v-table structures that the Component Object Model (COM) specification requires. C++ supports these constructs natively.

The C programming language does not support symbol namespaces, unlike C++. If your applications use both Collaboration Data Objects (CDO) and MAPI, you may experience duplicate symbol errors during compilation. Read the following section for more information:
