How to Download and Update Outlook 2016 64-bit

Outlook is a powerful application for managing your email, contacts, calendar, and tasks. It is part of the Microsoft Office suite, which also includes Word, Excel, PowerPoint, and more. If you have a Microsoft 365 subscription or a standalone version of Office 2016, you can use Outlook 2016 on your PC.

But did you know that there are two versions of Outlook 2016 that you can choose from? One is the 32-bit version and the other is the 64-bit version. The bitness refers to how much memory the application can access on your computer. The more memory, the better performance and functionality.

In this article, we will explain what is Outlook 2016 64-bit and why you might need it. We will also show you how to check which version of Outlook you have, how to download and install the 64-bit version of Outlook 2016, how to update it regularly, and how to troubleshoot some common issues with it.

What is Outlook 2016 64-bit and why do you need it?

Outlook 2016 64-bit is a version of Outlook that can access more memory than the 32-bit version. This means that it can handle larger files, more data sets, more add-ins, and more complex tasks without slowing down or crashing.

Benefits of using Outlook 2016 64-bit

Some of the benefits of using Outlook 2016 64-bit are:

• You can work with large data sets, such as enterprise-scale Excel workbooks with complex calculations, many pivot tables, data connections to external databases, Power Pivot, Power View, or Get & Transform.
• You can use add-ins with Outlook without worrying about running out of virtual address space. Add-ins are small programs that extend the functionality of Outlook, such as grammar checkers, encryption tools, or productivity boosters.
• You can work with extremely large pictures, videos, or animations in PowerPoint without compromising the quality or performance.
• You can work with files over 2 GB in Project, especially if the project has many sub-projects.
• You can develop in-house Microsoft 365 solutions like add-ins or document-level customization using the 64-bit version of Microsoft Office.

Drawbacks of using Outlook 2016 64-bit

Some of the drawbacks of using Outlook 2016 64-bit are:

• You need a computer that runs a 64-bit version of Windows. If your computer runs a 32-bit version of Windows, you cannot install or run the 64-bit version of Office.
• You may encounter compatibility issues with some older add-ins or macros that were designed for the 32-bit version of Office. You may need to update or replace them with newer versions that are compatible with the 64-bit version of Office.
• You may not notice any significant performance improvement if your computer has less than 4 GB of RAM or if you don’t work with large or complex files or data sets.

Therefore, you should consider the pros and cons of using Outlook 2016 64-bit before deciding to switch from the 32-bit version. If you are not sure, you can always try both versions and see which one works better for you.
