## レビュー

### "All-in-One Tool That Supports My Work, Learning, and Daily Life" — 5.0/5

> **Khushdeep** | *2026年7月3日* | 病院、ヘルスケア | おすすめ評価：9.0/10
> 
> **良いポイント**: Microsoft 365 has been very useful for both my professional and personal needs. I use it regularly for email, file storage, document creation, and sharing files with others. The biggest advantage is that everything is connected in one place, so it saves a lot of time and keeps my work organized.&#10;I use it for work-related tasks at The Brick, where I manage training documents, emails, and product information. I also used Microsoft tools while completing professional courses and learning new skills, including organizing notes and study materials.&#10;One of the most helpful features is file sharing and cloud access through OneDrive. I can access my documents from anywhere, whether I’m on my phone or laptop. This has been especially useful when coordinating tasks at work or quickly accessing files on the go.&#10;It has also been helpful in my personal life. My wife and I often use Word, Excel, and PowerPoint together for organizing information, planning, and keeping records in a structured way. The document tools make it easy to manage everything in one ecosystem.
> 
> **改善点**: Sometimes the subscription cost feels a bit high compared to basic alternatives. Also, the mobile apps are good for viewing and light editing, but for heavier work, the desktop version is much more efficient.
> 
> PowerPoint has been a useful part of both my professional and personal life. It has helped me organize ideas, study more effectively, create presentations that look professional, and even support my wife during an important stage of her career. It's easy to use, reliable, and packed with features that save time. I use it regularly and would confidently recommend it to anyone who wants to create professional presentations without a complicated learning process.

### "365 is great for office" — 5.0/5

> **Shane** | *2026年7月24日* | 倉庫 | おすすめ評価：9.0/10
> 
> **良いポイント**: Microsoft 365 is great especially since you can have all of the Microsoft tools in one place. Our business does everything with Microsoft so it helps a lot\!
> 
> **改善点**: Overall it has been good, I guess the only factor would be you need an internet connection but thats pretty much all cloud based systems
> 
> It has been great, I am able to bounce around from excel to outlook to word and have all my documents save in one place. Also can have multiple people working on same docs at once

### "Capable Enterprise Tool, but Hard to Justify Over Free Web Alternatives" — 3.0/5

> **Sourav** | *2026年8月8日* | 教育管理 | おすすめ評価：9.0/10
> 
> **良いポイント**: The seamless integration across the entire ecosystem is its strongest asset. Document management and file sharing via OneDrive and Teams allow for reliable real-time collaboration. Email management through Outlook handles high-volume communication smoothly, and native file conversion options in Word and Excel are straightforward. Once familiar with the interface, the overall ease of use is solid for advanced technical workflows.
> 
> **改善点**: The ongoing subscription cost feels hard to justify when free alternatives like Google Docs provide almost identical core capabilities directly in the browser with no installation required. For everyday document editing and collaboration, paying a recurring fee for desktop software feels redundant. Additionally, customer support for complex technical issues can be tedious and heavily automated.
> 
> Overall, Microsoft 365 is a feature-rich, enterprise-grade suite, but its value proposition is questionable for standard use cases. Free web-based platforms like Google Docs cover almost all daily document management, sharing, and writing needs without software downloads or monthly fees. Microsoft 365 remains useful primarily for environments that strictly require offline desktop power or specialized legacy tools.

### "M 365 Review" — 4.0/5

> **認証済みレビュアー** | *2026年5月29日* | 情報技術、情報サービス | おすすめ評価：9.0/10
> 
> **良いポイント**: Dashboard is very very simple and easy to use. Entra ID havig P2 licenses is very important that have access to all the security and Conditional access policies. Security features in this and exchange admin centre specifically to email related excellent and very easy to deploy. In the Entra portal and Security admin the default security score based on existing configured policies is very helpful and then suggestions how we can implement more and make the secure score more.
> 
> **改善点**: Support services now gets weak. Whenever you face an issue then you need to first reach out to the partner now from whom licenses are purchased. If issue is not resolved by the partner team then on your behalf they will raise a ticket to Microsoft which can take a lot of time now.

### "Reliable tool for everyday work" — 4.0/5

> **Alejandra** | *2026年8月20日* | 研究 | おすすめ評価：9.0/10
> 
> **良いポイント**: File sharing and collaboration are simple, and being able to access documents from my phone with the latest version that I did on my pc is very useful \!
> 
> **改善点**: The main contra for me is the price. It can feel a bit expensive, especially if you don't use all the apps included in the package
> 
> Very positive\! It is a reliable and practical solution for both individual and professional use. The apps work well together.
