Solution 1Recommended

Assign Mixed Licenses via Microsoft 365 Admin Center

Use the active users page in the admin center to apply both the Business Basic and F1 licenses to a single account.

Microsoft permits having multiple subscriptions in the same tenant. You can assign both Business Basic and F1 licenses to the same user, provided there are no direct service plan conflicts.

When assigning overlapping services, be mindful of duplicate sub-services to avoid unnecessary costs and ensure the user actually requires both plans.

Frequently Asked Questions

Can I mix enterprise and business plans in the same Microsoft 365 tenant?

Yes, Microsoft allows you to mix different types of plans, such as Business (like Business Basic), Enterprise, and standalone plans (like Exchange Online), within a single tenant and assign them to various users.

What happens if two assigned licenses have overlapping services?

If a user is assigned two licenses with overlapping services, Microsoft 365 will generally provide the features of the highest-tier plan. You may see notifications in the admin center about service conflicts, and certain duplicate sub-services may be disabled automatically.

Who is eligible for a Microsoft 365 F1 license?

The F1 license is specifically designed for Firstline Workers—employees whose primary role is to interact with customers or work directly with the product, typically without needing a dedicated desktop PC or full desktop applications.
