Why might you prefer Office 365 64-bit over Office 365 32-bit?

One reason is that you might want Office 365 64-bit because you prefer to be as up-to-date as possible. Depending on how you intend to use your Office 365 apps, their 64-bit versions might work better than the 32-bit ones. Here are the main reasons for which you should go with Office 365 64-bit:

  • You can work with very large Excel workbooks. For instance, you can work on Excel workbooks that have complex calculations, connect to external databases or are larger than 2 GB each.
  • You can work with large PowerPoint presentations, that have large pictures, videos at high resolutions and complex animations.
  • You can work with large Word documents that are not just about text. If they have large images or large tables, the Microsoft Word 64-bit version is going to perform better.

Of course, there are also drawbacks when using Office 365 64-bit: if you have some add-ins that were developed to work only in the 32-bit version of Office, they stop working in the 64-bit version. However, this is a situation that is mostly encountered in businesses where specific add-ins were created to fill specific needs. Home users or business users that do not use add-ins should not stumble upon such problems.
