What Is a Dynamics 365 Attach License?
A Dynamics 365 Attach License is a discounted license available to users who already have a qualifying base license for a Dynamics 365 application. It allows these users to access additional Dynamics 365 apps without paying full price for each one.
This model is ideal for users who need to work across multiple business functions, such as sales, customer service, finance, or operations, without the overhead of purchasing multiple full licenses.
Key Rules and Requirements
To take advantage of attach licensing, there are a few important rules to keep in mind:
- Base License Requirement: Attach licenses can only be assigned to users who already have a qualifying base license. For example, a user with a base license for Dynamics 365 Sales can attach a Customer Service license at a reduced cost.
- Additionally, the Base License SKU must be the highest-priced license among the applications assigned to that user.
- Named User Licensing: Attach licenses are assigned to individual named users. This means each user must be licensed separately, and licenses cannot be shared.
- Multiple Attach Licenses Allowed: A single user can have more than one attach license. This is particularly useful for roles that span multiple departments or responsibilities.
Pricing Overview and Examples
While pricing can vary slightly depending licensing terms, the picture below from Microsoft’s Dynamics 365 Licensing Guide gives a general idea of how attach licenses are priced compared to base licenses:

Additionally, it’s important to note that Microsoft offers “tenant attach” benefits for organizations with ten or more full Dynamics 365 users. This eligibility can qualify for highly discounted access to additional solutions like Dynamics 365 e-Commerce as well as Customer Service Insights, which includes:
- Customer Insights – Data, a customer data platform (CDP) that unifies and enriches data from across your business to deliver deep insights into customer behavior and preferences.
- Customer Insights – Journeys, which enables you to create and automate personalized customer journeys across channels like email, SMS, push notifications, and more.
