Strategic interoperability between competitors 1 Strategic interoperability between competitors By enabling the editing of ODT files in Office 365 via OneDrive, Microsoft is adopting a stance of technological openness. Although LibreOffice is a direct competitor, particularly on Windows, this compatibility makes life easier for users who juggle multiple formats. It addresses a reality: the ODT format is widely used in educational, public, and non-profit sectors. By integrating this feature, Microsoft is demonstrating that it prioritizes user experience over the format war. 2 A unified and accessible cloud experience The integration of ODT files into OneDrive allows documents to be centralized in the cloud, accessible from any device. Users can thus edit their LibreOffice files without installing third-party software, directly from their browser. This promotes collaboration, mobility, and productivity, while strengthening the appeal of Office 365 as a universal work platform, even for those who do not initially use Microsoft tools. 3 A Gateway to the Microsoft Ecosystem By allowing the editing of ODT files, Microsoft is creating a seamless gateway to its own ecosystem. LibreOffice users can take advantage of the advanced features of Office 365 (co-editing, sharing, automatic backup) without abandoning their original format. This strategy allows Microsoft to gradually appeal to a wider audience while respecting users' technological choices. It's a subtle way of transforming competition into complementarity.
