What is a CAL?
Client Access License — the key to legal access
A Client Access License (CAL) is a mandatory Microsoft license required to access Windows Server services. Without the correct number of CALs, using the server is not compliant with Microsoft licensing terms. A User CAL is assigned to a specific user, who can connect from any number of devices. It is the optimal solution when employees use multiple devices such as a laptop, tablet, and smartphone. One User CAL license grants access to all Windows Server instances within the organisation, not just one server.

Frequently asked questions
What is a User CAL?
A User CAL (Client Access License) is a Microsoft license that allows a specific user to legally access Windows Server 2019 services. A User CAL is assigned to the user and allows connections from any number of devices. Without the correct number of CAL licenses, using the server violates Microsoft licensing terms.
What is the difference between a User CAL and a Device CAL?
A User CAL is assigned to a user and allows that person to connect to the server from any number of devices. A Device CAL is assigned to a specific device, which can then be used by any number of users. A User CAL is better for mobile employees. A Device CAL is better for shared workstations and shift-based environments.
Do CAL 2019 licenses work with newer servers?
Windows Server 2019 CAL licenses are backward compatible, meaning they work with Windows Server 2019 and earlier versions. They are not compatible with newer server versions. If you plan a server upgrade, you should include the cost of new CAL licenses appropriate for the target server version.
What are the risks of not having CAL licenses?
Using Windows Server without the required number of CAL licenses is a breach of Microsoft licensing terms. During an audit, this may result in financial penalties, the need to purchase missing licenses at full list price, and potential legal complications. Microsoft licensing audits in Europe are becoming more frequent, so it is worth securing compliance in advance.
Can I transfer a User CAL to another user?
Yes, a User CAL can be transferred to another user, but not more often than once every 90 days. An exception applies if an employee leaves the company, in which case the transfer can be made immediately. Updating the assignment only requires a change in the license management tool.
Are the licenses original?
Yes, all licenses sold by Licensier are original Microsoft products with official activation keys. Every purchase is documented with a VAT invoice, which provides additional proof of legality in the event of a licensing audit. The keys are verified by Microsoft licensing systems.
How quickly will I receive the keys?
The activation keys for the 50 User CAL pack are delivered electronically within 5-30 minutes after payment confirmation. For payments via Klarna, PayPal, or SEPA instant transfer, delivery is nearly immediate. A traditional bank transfer requires additional time for the payment to be credited.
How many CAL licenses do I need?
For the User CAL model, count all users who will ever connect to Windows Server. Each user needs one User CAL regardless of how many devices they use. You should also include occasional users and external collaborators.
