What's the Difference Between Microsoft 365 Apps and Office LTSC 2021?

Microsoft 365 subscription plans offer a range of benefits, including access to Office applications and OneDrive storage. However, when it comes to choosing between Microsoft 365 Apps and Office LTSC 2021, there are some key differences to consider.

One of the main differences is that Microsoft 365 Apps are regularly updated with new features, sometimes as often as monthly. This means you'll always have access to the latest tools and capabilities. On the other hand, Office LTSC 2021 remains static with the same features it had at its initial release date in September 2021.

Another key difference is the way these options are sold. Microsoft 365 Apps are available through subscription plans that come with many Microsoft 365 enterprise and business plans. In contrast, Office LTSC 2021 can be purchased as a one-time license agreement, allowing you to install it on one computer per license.

In terms of security and bug fixes, both options receive updates during their lifecycle. This includes security fixes for vulnerabilities discovered by Microsoft's security team, as well as bug fixes for issues that arise. However, at the end of each product's lifecycle, Microsoft no longer provides these updates, and the product reaches 'end of support.'

So, what does this mean exactly? During its lifetime, a Microsoft product receives regular updates to keep it secure and reliable. At the end of its lifecycle, however, Microsoft stops providing these updates, leaving users vulnerable to security risks or potentially affecting compliance obligations.

For example, as of April 11, 2023, security updates and support for Microsoft Office 2013 will no longer be available, which could increase exposure to security risks or affect compliance obligations. If you're still using an Office 2013 client to connect to Microsoft 365, you may experience performance or reliability issues.

In summary, Microsoft 365 Apps offer regular updates with new features, while Office LTSC 2021 remains static with its initial release features. Understanding the differences between these options can help you make informed decisions about your organization's software needs and ensure you stay secure and compliant.
