32-bit app using 64-bit Outlook COM objects?

J

Jeff

Does anyone know if a 32-bit app can use Outlook COM objects that are
being served by a 64-bit version of Outlook 2010?

Thanks,
jb

I don't believe so, but you'd have to test that for yourself.

I wrote a 32-bit sample app, and it was able to do the following
against a Outlook 2010 x64 on Windows 7 x64:

Create the Application object
Create the NameSpace object
Call NameSpace.GetDefaultFolder()
Call MAPIFolder.Items.Count

So it looks like cross-bitness Outlook COM works.
