As we continue to rely on collaborative tools to drive productivity and innovation, we must ensure that our software and systems are compatible and up-to-date. CoAuthor, a powerful collaboration platform, is no exception. CoAuthor is only supported by supported versions of Microsoft 365 to guarantee uninterrupted collaboration and data safety.

Microsoft 365 is a dynamic ecosystem that continually evolves to provide users with the latest features, security updates, and technical support. However, this means that older versions of Microsoft Office eventually reach their end-of-life cycle. Office 2016, for instance, has reached the end of its mainstream support on October 10, 2023. This milestone marks the beginning of a gradual phase-out process, which will ultimately impact CoAuthor compatibility.

Using Office 2016 or other unsupported versions of Microsoft Office can lead to several issues:

1. No Connection to Microsoft 365 Services: Office 2016 can no longer connect to essential Microsoft 365 services like OneDrive for Business, SharePoint Online, and Exchange Online.

2. No Security Updates: After October 14, 2025, Office 2016 will no longer receive critical security updates, leaving your system vulnerable to potential threats.

3. No Technical Support: Microsoft customer service will cease providing technical support for Office 2016 after October 14, 2025.

Additionally, it's essential to note that CoAuthor is also not compatible with the web version of Microsoft Word. This means that users relying on the web-based application will need to switch to a supported desktop version or upgrade their subscription plan.

If testing in the customer environment isn't feasible or you're looking for a more permanent solution due to compatibility issues with unsupported versions or the web version of Microsoft Word consider upgrading your software. Upgrading to either Microsoft 365 - regardless of license type (Individual, Business Enterprise) - or Office Long Term Service Channel (LTSC) 2024 provides continued security updates and technical support from Microsoft.

In conclusion, CoAuthor is only supported by supported versions of Microsoft 365. To avoid compatibility issues and ensure uninterrupted collaboration, it's crucial to use a supported version of Microsoft Office. By doing so, you'll not only maintain data safety but also benefit from ongoing security updates and technical support from Microsoft.
