The Microsoft 365 (Office) app is now called the Microsoft 365 Copilot app across web (office.com, microsoft365.com), mobile (iOS, Android), and Windows. The new app name and icon reflects the integration of Copilot within the Microsoft 365 app.

The Microsoft 365 Copilot app continues to serve as your everyday productivity app for work and life. But in the era of AI and integration of Copilot, it's become much more than that. We've made several enhancements to innovate the work and education experience, as well as for consumers with a personal account.

The app remains your starting place to find, create, share, and collaborate in one place with access to your favorite productivity applications. This update represents the additional ways working with Copilot for tasks such as asking questions, creating content, drafting documents, and building agents with a work account.

1. Are you familiar with

Open Office by Apache? It's a clone. Very similar in nature to Office, but free!

2. Yes open source is the way to go. BUT, we prefer LibreOffice instead because...

of the following differences and reasons. And it's also free.

In 2025 and 2026, several regions and administrative bodies in Denmark, France, and Germany officially announced or completed transitions from Microsoft Windows and Office to Linux-based operating systems and open-source suites like LibreOffice.

Open Office it is widely considered obsolete because it has not had a major feature release since 2014. In contrast, LibreOffice is the more modern, actively developed successor that most users are encouraged to use.

Status of Apache OpenOffice

Stagnant Development: While maintenance releases occur, they focus on bug fixes, dictionary updates, and critical security patches rather than new features.

Security Concerns: The project has struggled with a "red" security status due to a lack of active developers, sometimes leaving vulnerabilities unpatched for over a year.

License Limitations: OpenOffice uses the Apache License, which prevents it from legally incorporating code from LibreOffice (which uses LGPLv3/MPL), whereas LibreOffice can and does incorporate code from OpenOffice.

Why LibreOffice is Considered Better

LibreOffice is generally superior for modern workflows due to the following advantages:

Frequent Updates: It receives regular major upgrades with new features and frequent security patches, backed by a much larger community of over 1,700 contributors compared to OpenOffice's small fraction of that.

Modern File Compatibility: LibreOffice provides robust support for modern Microsoft Office formats like .docx, .xlsx, and .pptx. OpenOffice can often open these files but may struggle to save or export them while preserving modern formatting.

Enhanced Performance: It offers a native 64-bit version and is optimized for modern hardware, including high-resolution (4K) displays. OpenOffice is often limited to 32-bit architecture on Windows.

Specialized Tools: Includes unique tools like a dedicated Chart application and a mobile remote for presentations.
For most users, LibreOffice is the recommended choice, while Apache OpenOffice is typically only relevant for legacy 32-bit systems or users who specifically prefer a 20-year-old interface style.
