Hi @Talal Gulam,
Thank you for posting your question to Microsoft Q&A Forum.

You do not need to make all 350 licenses the same type. Microsoft 365 licensing allows you to mix plans within the same tenant, provided each user is assigned a valid license that meets their needs.

with your proposed set up 300 users on Microsoft 365 Business Premium and 50 users on Microsoft 365 E3 or E5, this setup is fully supported and compliant. Many organizations use a mixed approach to provide advanced capabilities (such as enhanced security and compliance tools) only to roles that require them.

However, there is some crucial points you have to take note:

  • Business Premium is limited to 300 seats per tenant; your configuration keeps you at that cap.
  • Enterprise plans (E3/E5) do not have seat limits.
  • Features differ by plan. Users on Business Premium will not receive E3/E5-only capabilities (for example, certain advanced compliance features and analytics).

In conclusion, it is not required to move all 350 users to E3 or E5. Mixed licensing is both common and supported.

    You can have a mix of Microsoft 365 Business Premium licenses and Enterprise licenses (like E3 or E5) in your tenant, but there are some important considerations. Microsoft 365 Business Premium is designed for small to medium-sized businesses and is limited to a maximum of 300 licenses per organization. Therefore, if you have 350 users, you would need to ensure that the total number of Business Premium licenses does not exceed 300.

    For the remaining users, you would need to use Enterprise licenses (E3 or E5) to comply with the licensing requirements. It is not mandatory to make all 350 licenses E3 or E5, but you cannot exceed the 300 limit for Business Premium licenses.

    In summary, you can have 300 Business Premium licenses and the remaining users on E3 or E5 licenses, as long as you adhere to the licensing limits.
