How do Microsoft 365 licenses work?

Efficiency question :
Microsoft 365 licenses give each user access to the applications and services they need to do their job. However, not all licenses offer the same features, and not every employee in an organization needs exactly the same license.
A good strategy is therefore to identify the actual needs of different users before selecting licenses. The objective is to give the right people access to the right tools while avoiding paying for features that will not be used.
Key considerations:
Microsoft 365 includes several applications and services that vary depending on the license selected. Some licenses primarily provide access to office applications, while others add services for collaboration, security, device management, or other organizational needs.
The key is to understand what each group of users actually needs. Someone who mainly uses Outlook, Word, and Excel does not necessarily have the same needs as a manager, an IT administrator, or a user who requires more advanced features.
New features that may require additional licenses must also be considered, including certain artificial intelligence capabilities.
Non-profit organizations should also review the programs available to them before purchasing licenses. Microsoft licenses may be offered to them at reduced prices, which can lower the cost of their technology environment.
Challenges:
The main challenge is the growing number of products, license levels, and available features. Two licenses with similar names may provide access to different functionality.
Needs can also change. A new employee, a change in responsibilities, or the adoption of a new tool may require reviewing the license assigned to a user.
Microsoft 365 licensing should therefore not be treated as a one-time decision. Licenses should be reviewed periodically to ensure that they still match users' needs.
Technology:
Microsoft 365 includes applications such as Word, Excel, PowerPoint, Outlook, Teams, and OneNote, along with various cloud services and collaboration tools.
SharePoint and OneDrive can be used to store and share documents within the Microsoft 365 environment. Other Microsoft ecosystem solutions, such as Power BI, Power Apps, Power Automate, or Copilot, may require specific licenses or usage rights depending on the features used.
License selection should therefore consider the user's complete technology environment rather than a single application.
Developer's advice:
Before purchasing Microsoft 365 licenses, group users according to their actual needs. Assigning the same license to every employee simply to make administration easier may be unnecessary.
Start by listing the applications and features truly required for each type of user. Then determine which license provides access to them.
Also pay close attention to additional features you plan to deploy. Power BI, Power Apps, Power Automate, or Copilot can change licensing requirements depending on how these tools are used within the organization.
Finally, review your licenses periodically. A user who changes roles or no longer uses certain features may no longer need the same license level. Regular management helps align the Microsoft 365 environment more closely with the organization's actual needs.
