That comment demands clarification, because as stated it is quite 
misleading.

The issue here is that a 32-bit application can only load 32-bit DLLs.  
Outlook 2016 is a 32-bit application, so when it as a COM client tries 
to load an in-process COM server (that is, his add-in), the COM server 
DLL must also be 32-bit.

There are many, many ways that 32-bit and 64-bit programs can talk to 
each other.  This is a very specific instance.
