With the growing number of 64-bit Outlook users, rewriting 32-bit MAPI programs, add-ins, or macros for 64-bit Outlook is the preferred solution, although you can still use 32-bit Outlook if necessary.

Why choose the 64-bit version?

You’re dealing with big data sets, such as enterprise-scale Excel workbooks with sophisticated computations, several pivot tables, external database data connections, Power Pivot, 3D Map, Power View, or Get & Transform. In some circumstances, the 64-bit version of Office may perform better.

In PowerPoint, you’re working with incredibly big images, movies, or animations. The 64-bit version of Office may be better suited to handle these complex slide decks.
