This study aims to evaluate the effectiveness of the use of Artificial Intelligence (AI) in teachers' digital archiving through the Microsoft 365 ecosystem, specifically on the OneDrive and SharePoint platforms at SMPN 01 Tilamuta. The study used a qualitative approach with a descriptive evaluative method. Data were obtained through observations, interviews, and surveys of 15 teachers who participated in Microsoft 365 socialization and training. Analysis was conducted on four main dimensions, namely Microsoft 365, Microsoft Copilot, SharePoint, and OneDrive. The results showed that the use of Microsoft 365 obtained an overall average score of 73.29 with a good category. The Microsoft 365 dimension obtained the highest score of 78.17, followed by OneDrive with 74.05 and Microsoft Copilot with 71.43, while SharePoint obtained a score of 69.52 with a fair category. The findings also showed that the use of AI through Microsoft Copilot was able to improve teachers' work efficiency, where 53% of respondents felt time savings of more than 50% and 94% of respondents reported an increase in the quality of work results. Despite this, several challenges remain, such as limited user understanding, the need for further training, and concerns about data privacy and security. This study concluded that AI integration in Microsoft 365 through OneDrive and SharePoint effectively supports teachers' digital archiving, improves work efficiency, and simplifies document management and retrieval. However, optimizing SharePoint usage and improving user competency with AI features are still needed to achieve maximum benefits
