GqlMAPI

This project contains a library built with CppGraphQLGen which binds a GraphQL schema to MAPI.

The main purpose of this project is to demonstrate building a non-trivial C++ GraphQL service with CppGraphQLGen. It may also be useful in diagnostic and debugging tools for Microsoft Outlook. This library is not officially supported by Microsoft, but MAPI itself is still supported as a backwards compatible integration API for Microsoft Outlook.

Getting Started

You will need a Windows computer with a working installation of Microsoft Outlook for Windows, since that is how MAPI is installed. You can use any C++ compiler toolchain which fully supports C++17 on Windows, I recommend Visual Studio 2019 or Visual Studio Code with the CMake Tools and C/C++ extensions from Microsoft.

The build system uses CMake. If you are using Visual Studio 2019, it comes with a supported version of CMake (>= 3.17.1) pre-installed. You can also install CMake separately and then use it with another editor like Visual Studio Code or Vim.

You will also need to install CppGraphQLGen and GoogleTest separately to satisfy the CMake dependencies. The easiest way to do that is to use Vcpkg. See the Quick Start: Windows section of the Vcpkg README for more details.

Once you have Vcpkg installed and CMake is configured to use it, install the dependencies with a command like this:

> .\vcpkg\vcpkg install --triplet=x64-windows cppgraphqlgen gtest
