Get outlook contacts from C++ application

I need a C++ application to get Outlook contacts (from my local Outlook application)

What I have tried:

Hi,

I found this old example:
https://www.codeproject.com/Articles/3695/Importing-contacts-from-Outlook

But when I try to compile the code in my VS 2017 (once Outlook paths changed to mine) I get some errors in 'msoutl.tlh' file, autogenerated while compilation:

...
\msoutl.tlh(6015): error C3121: cannot change GUID for class 'Folder'
...
error C2556: 'AddressEntryPtr _AppointmentItem::GetOrganizer(void)': overloaded function differs only by return type from '_bstr_t _AppointmentItem::GetOrganizer(void)'
...
error C2371: '_AppointmentItem::GetOrganizer': redefinition; different basic types

Maybe I have something wrong in project configuration...

Any help?

Thanks,
Diego

Solution 1

Delete all temporary files and "Rebuild All". If that doesnt work: close Visual Studio re-delete and also delete the temp files in the solution folder. (Some databases) Check the timestamp to find them.

It can also be that Microsoft had changed the interface of some functions, so carefully read the documentation of it.

Just if usefull for anyone, I found how to compile the code here:

https://docs.microsoft.com/es-es/office/troubleshoot/office-developer/automate-outlook-2010-using-c-with-mfc

Just add to the import line:

... rename("Folder", "OlkFolder") rename("CopyFile", "OlkCopyFile")` rename("GetOrganizer", "GetOrganizerAE")

to avoid the compilation errors
