MAPIInitialize() fails with MS outlook 365

Hi

I have an VC++ application which reads the emails from the MS outlook.

Till now it was working fine till I was using MS outlook 2019/2016.

But as soon as I upgraded my outlook to office 365 app, my application fails with outlook.

below is the code chunk:

LPMAPISESSION			m_pSession;

MAPIINIT_0 MAPIINIT = { 0, MAPI_MULTITHREAD_NOTIFICATIONS };

	// Initialize MAPI
	flags = MAPI_NEW_SESSION | MAPI_USE_DEFAULT;
	hr = ::MAPIInitialize(&MAPIINIT);
	if (SUCCEEDED(hr))
	{
		hr = MAPILogonEx(0, NULL, NULL, flags, &m_pSession);
	};

The API which is failing is MAPIInitialize(). Now it is returning error code 127 (The specified procedure could not be found.)

Environment is Visual Studio 2019/2022, I tried with both.

Please suggest is there any change in the libraries of MAPI for outlook 365.

32-bit compilation is only I am trying to run, but I did compiled in 64-Bit, there I was getting the error "fatal error LNK1112: module machine type 'X86' conflicts with target machine type 'x64'". So I switched back to 32bit. Any idea how to get rid of this error in 64 bit compilation?

Kindly help, my application has stopped working and need guidance.

Thanks in advance.
