FAQ: Microsoft Windows Server 2019 50 User CAL

What is Microsoft Windows Server 2019 50 User CAL?

Microsoft Windows Server 2019 50 User CAL is a package of 50 user access licenses (User CAL) for the Windows Server 2019 environment. It is not a program or installation media, but a licensing document that authorises specified users to legally access the server. This product is used to regulate access rights to server services in a company, office, or other organisation using Microsoft Windows Server.

What does the CAL abbreviation mean?

CAL is an abbreviation for Client Access License, or client access licence. In practice, this means that a Windows Server licence for the server alone is not sufficient for users or devices to use the server's resources in accordance with Microsoft's rules. Additional CALs are required. In this offer, we are referring to User CAL, or licences assigned to specific individuals, rather than devices.

Is this downloadable software or an activation key?

No. This is a very important distinction. Microsoft Windows Server 2019 50 User CAL is not installation software and does not work like a classic program that can be run on a computer. It is a legal licence that confirms the right of access to the server for 50 users. Depending on the sales model, the customer receives licensing documents, data confirming the legality of the purchase, and a sales document. If you need an explanation of what the delivery or documentation looks like, you can contact us by phone at 00 800 121 1654.

What is the difference between User CAL and Device CAL?

User CAL is assigned to a user. This person can connect to the server from multiple devices, such as a desktop computer, laptop, and work phone, as long as they are the licensed user.
Device CAL is assigned to a device. In this case, multiple people can use the same computer, terminal, or other equipment, but the licence applies to that one device.

The choice depends on the work model:

if one employee uses multiple devices, User CAL is usually more cost-effective,
if multiple people work shifts on one workstation, Device CAL is often better.

The 50 User CAL package is therefore a good solution for organisations where the number of employees with access to the server matters, not the number of workstations.

How many CALs do I need in practice?

You need as many licences as the number of users who will have access to Windows Server services. If 37 employees use the server, you should have at least 37 User CAL licences. In the case of a 50 User CAL package, you can licence up to 50 specific users.

It's worth remembering that licensing applies to actual access, not just daily active work. If a user has the right to use server resources, directories, domain services, shared applications, or other Windows Server functions, they should be covered by the appropriate licence. For licensing compliance, it's best to count all users who have or will have access to the environment.

Does this product also apply to RDS?

This needs to be distinguished very precisely. A standard Windows Server CAL gives the right to access Windows Server, but does not replace the RDS CAL licence if users are using remote desktop services in a model that requires separate RDS permissions. If the environment includes remote sessions, terminals, or desktop/application publishing through Remote Desktop Services, it may be necessary to purchase the relevant RDS CAL.

Therefore, before purchasing, it's worth determining whether you need:

only Windows Server User CAL,
or also additional RDS licences.

Are CAL licences mandatory from a compliance perspective?

Yes. This is an element of Microsoft's licence compliance. Having only a server licence without the appropriate number of CALs may mean incomplete or non-compliant licensing of the environment. In the event of a control or audit, it's important not only that the server is running, but also that user access has been properly regulated.

For this reason, it's worth storing:

the purchase document,
licence specification,
VAT invoice,
proof of origin and legality of the product.

Such documentation helps to demonstrate that access to Windows Server 2019 has been licence-secured in accordance with the manufacturer's conditions.

Can the licence be transferred to another user or to another company?

In principle, the assignment of a User CAL licence should be treated as an assignment to a specific user within the organisation, and changes should be made in accordance with Microsoft's licence conditions. In practice, licences should not be randomly "rotated" between many people from day to day just to reduce the number of required permissions.

If it comes to transferring to another entity, company, or resale, one should always consider the conditions of the specific licensing channel, Microsoft's rules, and the complete set of documents confirming the legal origin. Therefore, in the case of questions about transfer or change of assignment, it's best to consult the specific scenario before purchasing.

How do I know if the key or licence is legal?

Legality should be assessed not only by the "key" itself, but primarily by the entire licensing basis. In the case of CAL, the most important thing is that the product comes from a legal source and is sold with the relevant commercial documentation and information about the type of licence. The customer should receive clear confirmation of what the purchase concerns: the number of licences, product version, and type of access.

When purchasing, pay attention to:

the consistency of the product name with the offer,
the legal origin of the licence,
the sales document,
the possibility of receiving a VAT invoice,
clear rules for delivery and after-sales service.

What does the delivery look like and what documents will I receive after purchase?

In the case of this type of product, delivery usually has an electronic character, since we are talking about an access licence, not physical software. The customer receives the information needed to document the purchase and the held licence entitlement. Standardly, an important element of the transaction is also the VAT invoice, which confirms the purchase in business transactions.

If you want to confirm the details of the delivery, the form of documents, product availability, or the method of order execution, please contact the service at 00 800 121 1654 or send an email to [email protected].

Is 50 User CAL sufficient for a growing company?

It depends on the number of users who need to access the server now and in the near future. The 50 User CAL package works well where an organisation wants to immediately organise licensing for a larger group of employees and avoid purchasing individual permissions every few weeks. However, if rapid employment growth or the implementation of new server services for additional departments is planned, it's worth considering future demand from the outset.

When planning, it's best to adopt a simple rule: we license all users who are to have access to Windows Server, even if they don't use it all the time. This keeps the environment transparent, secure, and compliant in terms of licensing.
