## レビュー

### "Solid suite, but the value depends on how deep you go" — 4.0/5

> **Blake** | *2026年5月22日* | 小売 | おすすめ評価：8.0/10
> 
> **良いポイント**: The integration between apps like Word, Excel, Teams, and Outlook is genuinely seamless. Everything just talks to each other without a lot of setup headaches. OneDrive syncing has been reliable for the most part, and being able to access files from any device has been a real quality-of-life improvement. It's hard to imagine going back to managing everything locally.
> 
> **改善点**: However, the prices seem to be slightly intimidating when using them per person in case of a bigger team since they accumulate very quickly. Certain capabilities may be hidden in menus or can be used exclusively by the users of higher-paid versions, which is somewhat disappointing for those who expect the full range of functionality. Occasionally occurring mandatory upgrades interrupted my work.
> 
> On the whole, Microsoft 365 delivers on its promises. All information stays structured and available to access wherever I may be working from. You have to learn how to make use of all of its features, but after getting past that learning period, you'll find yourself comfortable using it. I would suggest it for most companies as long as you're willing to stick with its ecosystem.

### "icrosoft 365 — the backbone of our daily operations" — 4.0/5

> **Louis** | *2026年5月22日* | 不動産 | おすすめ評価：7.0/10
> 
> **良いポイント**: Seamless integration: All apps work together flawlessly, which significantly improves productivity and collaboration across teams.&#10;Cloud-based \&amp; cross-device: Access to files, emails, and tools from any device, anywhere, with automatic synchronization via OneDrive and SharePoint.&#10;Collaboration features: Real-time co-authoring in Word, Excel, and PowerPoint, combined with Teams for communication, makes remote and hybrid work effortless.&#10;Email management with Outlook: Powerful spam filtering, calendar integration, and rules/automations make handling high email volumes manageable.&#10;Security \&amp; compliance: Enterprise-grade security, MFA, conditional access, and data loss prevention give peace of mind, especially when handling sensitive data.&#10;Regular updates: Microsoft consistently adds new features (especially with Copilot AI integration), keeping the suite modern and relevant.
> 
> **改善点**: Admin complexity: The Microsoft 365 Admin Center and related portals (Azure AD/Entra, Exchange Admin, Teams Admin, etc.) can be overwhelming and fragmented. Finding the right setting often requires navigating multiple consoles.&#10;Licensing structure: The different plans (Business Basic, Standard, Premium, E3, E5, etc.) can be confusing, and some essential features are locked behind higher-tier licenses.&#10;Teams performance: Teams can be resource-heavy and occasionally sluggish, especially on older machines.&#10;Customer support: Support quality is inconsistent — simple issues are handled well, but more complex technical problems can take time to resolve and require escalation.
> 
> ur overall experience with Microsoft 365 has been very positive. It has become indispensable for our daily operations, providing a unified environment for communication, collaboration, and document management. The combination of productivity apps, cloud storage, and enterprise-grade security delivers excellent value for money.

### "Powerful Tools, but Often Complicated" — 3.0/5

> **Michael** | *2026年6月11日* | 卸売 | おすすめ評価：4.0/10
> 
> **良いポイント**: Microsoft 365 includes a comprehensive set of applications that cover just about every business need. The integration between tools like Outlook, Excel, Word, Teams, and OneDrive is a major strength.
> 
> **改善点**: Many parts of Microsoft 365 feel more complicated than they need to be. The interface can be inconsistent between applications, and some areas still show their age from a UI perspective. The sheer number of features and settings can also make simple tasks harder to find and accomplish than they should be.
> 
> Overall, Microsoft 365 is an incredibly capable productivity suite that offers virtually every tool a business could need. However, that depth comes with a tradeoff.

### "Its just the standard Office software product" — 4.0/5

> **認証済みレビュアー** | *2026年4月24日* | 運輸、トラック、鉄道 | おすすめ評価：8.0/10
> 
> **良いポイント**: The best thing about Microsoft 365 is that everyone uses it \&amp; knows how to use it. You don't have to train anyone on using the features.
> 
> **改善点**: The support offered via Microsoft is poor \&amp; getting something changed or fixed can be impossible. Luckily third party companies can assist with most issues.
> 
> The suite of software enables the business to collaborate together using email, sharepoint or teams. Its easy to pick up the basics \&amp; the advanced features can be used without too much effort. The monthly fee is low compared to the features offered.

### "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.
