One of the most significant aspects of the MS-900 exam—and a major focus area—is the suite of applications and services that make up Microsoft 365. These services are designed to enable individuals and organizations to work more efficiently, collaborate in real time, and manage content securely across devices. Understanding how these tools function and support business workflows is critical for exam success and for gaining practical knowledge of Microsoft’s productivity ecosystem.
At the heart of Microsoft 365 is a collection of productivity applications that most users are already familiar with in some form. These include Microsoft Word for document creation, Excel for spreadsheets and data analysis, PowerPoint for presentations, Outlook for email and calendaring, and OneNote for note-taking. These tools are enhanced and extended in Microsoft 365 with cloud connectivity, allowing real-time co-authoring, auto-save, and seamless file sharing through OneDrive.
Microsoft 365 is available in various plans, including offerings tailored to personal use, small to medium-sized businesses, and large enterprises. These plans include desktop and web-based versions of the applications, ensuring accessibility regardless of device or location.
Beyond these core applications, Microsoft 365 provides services that enable collaboration and team-based work. Microsoft Teams is a central hub for teamwork that combines chat, video conferencing, file sharing, and app integration. It allows users to create channels, host meetings, and connect with external stakeholders through guest access. Teams is integrated with other services such as SharePoint, which provides the backend for file storage, and Outlook, which syncs calendar and email functionalities.
SharePoint itself is another key component of Microsoft 365. It is used to create intranet sites, manage documents, and support workflows. Teams often uses SharePoint document libraries for file storage, which helps in enforcing consistent access controls and permissions.
Another important application is OneDrive, a cloud-based file storage solution. OneDrive allows users to store personal and shared documents and access them from any device. For businesses, OneDrive ensures that files are always available, even if the original device is lost or damaged. Users can control who sees their files and can collaborate in real time with colleagues.
Microsoft 365 also includes a wide array of task and project management tools. Microsoft Planner provides a simple, card-based task management system, allowing teams to organize work visually.

Microsoft 365 addresses this challenge by providing tools that support zero-touch provisioning, automated updates, and mobile device management.
Windows 365 and Azure Virtual Desktop are two services that offer virtual desktops through the cloud. These platforms allow users to access a full Windows experience from virtually any device, which enhances flexibility and scalability for businesses. The MS-900 exam requires an understanding of the differences between these services and when each might be used.
Windows 365 is a simplified virtual desktop offering, often targeted at smaller organizations or individual users who need persistent desktops. Azure Virtual Desktop, on the other hand, is more flexible and suitable for complex, enterprise-level deployments where administrators require more control over infrastructure and scaling.
Microsoft 365 includes robust analytics capabilities through services like the Microsoft 365 admin center and Viva Insights. The admin center provides detailed reports on service usage, license assignment, user activity, and app adoption. Viva Insights, on the other hand, helps individuals and managers understand work patterns, identify burnout risks, and improve productivity through data-driven insights.
Reports in Microsoft 365 are crucial for decision-making. For example, a report showing low Teams adoption in a specific department could prompt training sessions or workflow adjustments. Similarly, insights into OneDrive storage trends can help IT teams manage capacity and plan for future needs.
Another important area covered in the MS-900 exam is the deployment and update model for Microsoft 365 Apps. Organizations can choose from several update channels—Current Channel, Monthly Enterprise Channel, and Semi-Annual Enterprise Channel—each offering a different balance between feature updates and stability. Deployment rings are also used to roll out updates in phases, starting with a small pilot group before full-scale deployment.
By using these models, IT administrators can manage risk, ensure compatibility with internal applications, and give users a consistent experience across devices. Understanding how Microsoft delivers updates and manages application lifecycles is essential for ensuring security and functionality in a dynamic workplace environment.
When studying for the MS-900 exam, candidates should be prepared to explain how these services and features work, how they integrate with one another, and what business problems they solve. This includes recognizing the differences between individual applications, identifying use cases, and understanding licensing implications.
Many organizations rely on Microsoft 365 for secure document management, efficient communication, and seamless collaboration. Being familiar with these capabilities not only helps candidates succeed in the MS-900 exam but also prepares them to contribute more effectively in any Microsoft 365-powered environment.
Microsoft 365 Security, Compliance, Privacy, and Trust
As organizations move more of their operations to the cloud, security and compliance become top priorities. Microsoft 365 is built with these concerns in mind and includes a comprehensive set of tools and features that ensure the safety of data, manage regulatory compliance, and support privacy and trust requirements. For candidates preparing for the MS-900 exam, understanding these security and compliance fundamentals is essential.
One of the primary concerns for any business is protecting user identities. Microsoft Entra ID (formerly Azure Active Directory) serves as the identity and access management platform for Microsoft 365. It allows organizations to manage user authentication, enforce access policies, and secure credentials. Microsoft Entra ID supports multiple identity models, including cloud-only identity, on-premises identity using directory synchronization, and hybrid identity where users can access resources both on-premises and in the cloud.
Key features of identity protection include multi-factor authentication (MFA), which requires users to provide two or more verification methods before gaining access to accounts. This greatly reduces the risk of unauthorized access due to stolen or compromised credentials. Self-service password reset (SSPR) allows users to reset their own passwords securely, reducing help desk workload and improving user productivity.
Conditional access is another core component of Microsoft’s identity security strategy. It allows administrators to enforce policies based on signals like user location, device health, or application being accessed. For example, a company might require MFA only when users are signing in from outside the corporate network or from an unmanaged device. These policies help ensure that only the right people under the right conditions can access sensitive data.
Microsoft 365 also includes an integrated suite of threat protection solutions under the Microsoft Defender brand. Microsoft Defender for Endpoint helps detect and respond to attacks on user devices, while Defender for Office 365 protects emails and collaboration tools from phishing, malware, and unsafe links. Defender for Identity monitors on-premises directories for suspicious activities, and Defender for Cloud Apps ensures secure usage of SaaS applications. These services work together to form Microsoft Defender XDR (Extended Detection and Response), which offers a coordinated response to complex security threats.
One of the useful features for administrators is the Microsoft Defender Portal. It provides a centralized interface for viewing alerts, analyzing incidents, and configuring policies across all Defender products. Through the portal, security teams can prioritize threats, investigate root causes, and take corrective action faster.
Another powerful tool in the security toolkit is Microsoft Secure Score. This feature evaluates the security posture of an organization and provides recommendations for improvement. Secure Score analyzes settings, user behavior, and system configurations across Microsoft 365 services, assigning a score that helps measure progress over time. By acting on the suggestions, organizations can proactively strengthen their defenses.
Compliance is another major area of focus for Microsoft 365. Businesses must comply with a wide range of legal and regulatory requirements related to data protection and privacy. Microsoft supports compliance through a combination of features under the Microsoft Purview brand. Microsoft Purview Information Protection helps classify, label, and protect sensitive data using tools like sensitivity labels and data loss prevention (DLP). These features can automatically apply protection rules to documents and emails, ensuring that confidential data does not leave the organization unintentionally.
Microsoft Purview also includes capabilities for eDiscovery and audit. eDiscovery allows organizations to identify and retrieve electronic information that may be relevant in legal cases or internal investigations. Audit logs provide a record of user and administrator actions across Microsoft 365 services, which is critical for understanding what happened during a security incident or for meeting regulatory reporting obligations.
Insider risk management is another area supported by Microsoft Purview. It helps organizations identify potentially harmful behavior by users, such as data leaks, policy violations, or security breaches caused by human error or malicious intent. By analyzing user actions and applying machine learning, insider risk tools can flag suspicious patterns and help prevent costly incidents.
Trust is central to Microsoft’s approach to cloud services. The company adheres to global compliance standards, including the General Data Protection Regulation (GDPR), Health Insurance Portability and Accountability Act (HIPAA), and ISO certifications. Microsoft maintains a public Trust Center where customers can find documentation about how data is handled, stored, and protected in Microsoft 365.
Microsoft also follows the Zero Trust security model, which assumes that no user or device is inherently trustworthy. Instead, access is granted based on continuous verification of identity, device health, and other contextual signals. This model emphasizes minimizing access, segmenting networks, and logging all activity to reduce the attack surface and limit the impact of breaches.
Privacy is another cornerstone of Microsoft 365’s architecture. Microsoft Priva is a privacy management solution that helps organizations protect personal data, fulfill regulatory obligations, and build user trust. Priva helps identify personal data across Microsoft 365 environments, manage data subject requests, and assess the risks associated with data processing.
Data residency and data sovereignty are important considerations for businesses operating in multiple regions. Microsoft 365 provides options to store data in specific geographic locations to comply with local laws. Customers can select data regions when provisioning services, and Microsoft guarantees that certain types of data will remain within those boundaries.
Support for service level agreements (SLAs) ensures that Microsoft maintains high levels of service availability. SLAs define the expected uptime for services like Exchange Online, SharePoint Online, and Teams, and include provisions for service credits if availability falls below agreed thresholds. Organizations can monitor service health through the Microsoft 365 admin center, where they can check the status of services, view advisories, and submit support tickets.
Support is an essential part of maintaining secure and compliant Microsoft 365 environments. Organizations can create support requests through the admin center, where different tiers of support are available depending on the licensing agreement. Enterprise customers may receive dedicated support contacts, faster response times, and access to Microsoft FastTrack resources for deployment assistance.
Understanding the Microsoft 365 security, compliance, privacy, and trust features is not just about passing the MS-900 exam. It equips IT professionals, administrators, and business leaders with the knowledge to make informed decisions about risk management, data protection, and regulatory compliance. These skills are increasingly in demand as organizations seek to protect customer data, meet legal obligations, and maintain trust in their digital services.

Support for Microsoft 365 is available through various channels. Organizations can create support requests directly in the admin center. The level of support received depends on the type of subscription and whether the organization has a support plan in place. Basic support typically includes access to self-help resources, while more advanced plans may offer 24/7 support, dedicated account managers, and technical account support for mission-critical environments.
Service level agreements (SLAs) are formal commitments made by Microsoft regarding the availability of services. These SLAs typically promise a service uptime of 99.9% or higher. If Microsoft fails to meet the SLA, customers may be eligible for service credits. These agreements provide reassurance to organizations that rely heavily on cloud-based productivity tools.
Monitoring service health is an ongoing task for administrators. Microsoft 365 includes a Service Health dashboard in the admin center where IT teams can view real-time status updates, planned maintenance windows, and past incidents. This helps organizations quickly identify issues and communicate with their users when necessary.
Service continuity is another key consideration. Microsoft designs its data centers with redundancy and failover capabilities to ensure services remain available even in the event of localized failures. Additionally, tools such as backup and restore options for SharePoint Online and Exchange Online help protect against accidental data loss.
Another important concept to understand in the context of Microsoft 365 pricing and licensing is the distinction between base licensing and add-on licensing. A base license provides access to a bundle of core services, while add-on licenses extend or enhance those services for users who need more capabilities. This modular approach allows organizations to control costs while still delivering specialized functionality to users who need it.
Microsoft offers tools to help organizations estimate costs and choose the right plan. The pricing calculator allows administrators and finance teams to enter the number of users and services they require, and then view estimated costs for various licensing scenarios. This is particularly useful during budget planning or when scaling up services.
Educational institutions and nonprofits may qualify for discounted or special licensing terms. Microsoft provides specific plans for academic and nonprofit organizations, offering the same services at a reduced cost or even free for qualifying institutions. These programs help expand access to productivity and collaboration tools without placing a financial burden on resource-constrained organizations.
Lastly, the Microsoft FastTrack program is available to help organizations onboard to Microsoft 365 services.
