After migrating to VS 2013 C++ Outlook add-in throws error MSB6006: "CL.exe" exited with formula –1073741515

Recently I tried migrating the C++ Outlook add-in project ( This project was created in Visual Studio 2010 and we tried migrating to Visual Studio 2013. 

During compilation, I encountered the following error:

 error MSB6006: "CL.exe" exited with formula –1073741515

The same code compiled, worked successfully in Visual Studio 2010. We haven’t done any changes in Visual Studio 2013, but still we got the above error. 

I fixed the issue by changing the Platform Toolset value and it helped me to compile successfully.  I tried the following (refer the snapshot): Changed Platform Toolset value to Visual Studio 2013.


Happy debugging
