Sample Code

#include <stdio.h>
#include <tchar.h>

#import <cdo.dll> no_namespace
#import "c:\\Program Files\\Microsoft Office\\Office\\Addins\\esconf.dll" no_namespace

struct StartOle {
    StartOle() {CoInitialize(NULL);}
    ~StartOle() {CoUninitialize(); }
} _inst_StartOle;

void dump_com_error(_com_error &e)
{
  _tprintf(_T("Oops - hit an error!\n"));
  _tprintf(_T("\a\tCode = %08lx\n"), e.Error());
  _tprintf(_T("\a\tCode meaning = %s\n"), e.ErrorMessage());
  _tprintf(_T("\a\tWcode = %08lx\n"), e.WCode());
  _bstr_t bstrSource(e.Source());
  _bstr_t bstrDescription(e.Description());
  _tprintf(_T("\a\tSource = %s\n"), (LPCTSTR) bstrSource);
  _tprintf(_T("\a\tDescription = %s\n"), (LPCTSTR) bstrDescription);
}

void main (void)
{
    try {
        // Setup MAPI session
        _SessionPtr pSession("MAPI.Session");
        pSession->Logon("YourProfileName");

        // Setup Events object
        IEventsPtr pEvents("MSExchange.Events");
        pEvents->put_Session(pSession->GetMAPIOBJECT());

        // Get pointer to Inbox
        _variant_t vInbox(pSession->GetInbox());

        // Get BoundFolder and associated Event Bindings
        IBoundFolderPtr pBoundFolder(pEvents->GetBoundFolder(&vInbox, true));
        IEventBindingsPtr pBindings(pBoundFolder->GetBindings());

        // Create new event binding 
        IEventBindingPtr pBinding(pBindings->Add());
        _bstr_t bstrName("TestBinding");
    
        pBinding->PutName(bstrName);
        pBinding->PutActive(true);
        // EventMask:   None = 0,
        //      ScheduledEvents = 1,
        //      NewItemEvents = 2,
        //      ChangedItemEvents = 4,
        //      DeletedItemEvents = 8,
        //      AllEvents = 65535 
        pBinding->PutEventMask(1); // ScheduledEvents

        // The following is the proper class ID for events based on the 
        // standard Event Scripting Agent, if you are using a custom
        // event handler, you should specify it's class ID here instead.
        pBinding->PutHandlerClassID("{69E54151-B371-11D0-BCD9-00AA00C1AB1C}");

        ISchedulePtr pSchedule(pBinding->GetSchedule());
        // ScheduleType: 
        //      ScheduleTypeUnknown = 0,
        //      ScheduleTypeHourly = 1,
        //      ScheduleTypeDaily = 2,
        //      ScheduleTypeWeekly = 3
        pSchedule->put_Type((long)1); //Hourly
        pSchedule->PutInterval((long)60); //60 minutes

        pBinding->SaveChanges();
        pBoundFolder->SaveChanges();

        _tprintf("TestBinding installed\n");
        
        pSession->Logoff();  
    }
    catch (_com_error &e)
    {
        dump_com_error(e);
    }
    return;
}
                

Please note that to bind an agent to Exchange Server Mailbox Folder, you must have at least Author permissions on the EventConfig_servername object in the Exchange Server directory.
