Join nowIn today's flexible working environment, your team accesses critical business applications from a multitude of devices. A single employee might start their day on a desktop in the office, continue working on a laptop during their commute, and check emails from a tablet in the evening. The Windows Server 2016 User Client Access License (CAL) is the definitive licensing solution designed for this exact scenario. Instead of counting every device, you license the individual user. This 50-pack provides a volume-priced, perpetual licence for 50 named users, granting each person the legal right to access your Windows Server 2016 Standard or Datacenter environment from an unlimited number of personally operated devices. It is the most cost-effective and administratively simple way to achieve Microsoft licensing compliance for organisations with a mobile, flexible, or hybrid workforce, eliminating the complexity of device-based counting and ensuring your team stays productive from anywhere.
Your order from Lizensa includes everything required to bring your organisation into full compliance. You will receive a genuine Microsoft Windows Server 2016 User CAL licence, delivered instantly via email. This is a pure licensing right; there is no physical media or individual licence key to install on each workstation. Instead, you receive an official licence certificate and documentation that serves as your proof of purchase and legal entitlement during a Microsoft audit. The licence is perpetual, meaning it does not expire and remains valid for the lifetime of your Windows Server 2016 servers. Activation of the server itself is handled separately, and these CALs do not require a technical activation process on the client side—compliance is managed through accurate record-keeping. Your purchase includes a downloadable VAT invoice, suitable for tax deduction and B2B reverse-charge mechanisms, and a comprehensive guide explaining how to document your CAL assignment for audit purposes. This licence is compatible with Windows Server 2016 Standard and Datacenter editions and supports all available interface languages.
Choosing the correct Client Access Licence is critical for both compliance and budget. Microsoft offers two primary CAL models for Windows Server 2016, and the optimal choice depends entirely on your organisation's working patterns.
User CAL (this product): A User CAL is assigned to a specific person. This model is superior when your employees access the server from multiple devices. For example, if a graphic designer uses a powerful desktop, a laptop for client meetings, and a phone for after-hours email, a single User CAL covers all three access points. It is the recommended choice for organisations with mobile employees, hot-desking environments, or Bring Your Own Device (BYOD) policies. User CALs also simplify administration because you only need to count employees, not the rapidly changing inventory of corporate devices.
Device CAL: A Device CAL is assigned to a specific workstation or device. This model is more economical when multiple users share a single device, such as in shift-work scenarios on a factory floor, a retail point-of-sale terminal, or a hospital nursing station computer. If three shifts of workers use the same terminal to access Windows Server services, only one Device CAL is needed for that terminal, rather than three User CALs.
For the majority of modern knowledge workers who use more than one device, the User CAL provides the greatest flexibility and is the most cost-effective licensing path. This 50-pack of User CALs is specifically designed to equip a department or medium-sized business where each employee operates in a multi-device world.
This product is a licensing right and does not have hardware requirements for the client devices. However, to utilise this licence, your server infrastructure must meet the following criteria:
As a licence-only product, there is no software to install on the 50 individual user devices. Upon completing your purchase, you will receive an email from Lizensa within an average of 60 seconds containing your official licence documentation, proof of entitlement, and a detailed VAT invoice. There is no licence key to enter for each CAL. Instead, you must maintain a clear record of the 50 named users to whom these CALs are assigned, ready for presentation during a Microsoft software asset management review. Your server software itself must be activated with its own distinct licence key. Should you have any questions about properly documenting your CAL assignments for audit compliance, Lizensa's multilingual technical support team is available free of charge to guide you through the process. As a perpetual licence, you are entitled to reassign a User CAL from one employee to another permanently leaving the organisation after 90 days, ensuring your investment remains flexible.
Securing your Microsoft infrastructure requires a licensing partner you can trust implicitly. At Lizensa, we have built our reputation on delivering genuine, verified software licences sourced directly from authorised European distribution channels. When you purchase this Windows Server 2016 50 User CAL pack, you are not just buying a document; you are investing in complete peace of mind. Your licence arrives via instant digital delivery, with the confirmation email typically landing in your inbox in under a minute, allowing you to address compliance gaps immediately. Every transaction is protected by full EU consumer rights, including a 14-day refund guarantee, and is processed through a Stripe-secured checkout that supports SEPA, iDEAL, BLIK, Google Pay, and major credit cards. We automatically provide a detailed VAT invoice with every order, facilitating seamless B2B accounting and reverse-charge eligibility across all 27 EU member states. Should any question arise, our free multilingual support team is ready to assist, ensuring your experience is smooth from purchase to audit.
This is a one-time, perpetual purchase. The Windows Server 2016 User CAL does not expire and remains valid for the entire lifetime of your Windows Server 2016 deployment. You will not be charged any recurring fees.
A User CAL licenses a specific person to access the server from any device (PC, laptop, phone). A Device CAL licenses a specific device to be used by any number of users. User CALs are best for mobile employees with multiple devices, while Device CALs are more economical for shared workstations used by shift workers.
Our system delivers licences instantly. On average, the email containing your official licence documentation and VAT invoice arrives in under 60 seconds, allowing you to begin your compliance documentation immediately.
Absolutely. Lizensa supplies only 100% genuine, verified licences sourced from authorised European distributors. You will receive official documentation that serves as valid proof of ownership during a Microsoft software asset management audit.
No. Windows Server CALs are a legal licensing right, not a software key. There is no technical activation for CALs. You simply maintain accurate records of your assigned users, which is your proof of compliance.
Yes. Microsoft's licensing terms allow you to permanently reassign a User CAL from one user to another after 90 days. This ensures your perpetual licence investment adapts to staff turnover.
A Windows Server User CAL permits a user to access a server, but using Microsoft's full Remote Desktop Services (RDS) functionality requires an additional RDS CAL. This is a separate licence and is not included in this pack.
No. Windows Server 2016 CALs provide access to servers running 2016 and older versions (like 2012 R2) via downward compatibility. To access a Windows Server 2019 or 2022 instance, you must purchase the corresponding CAL version.
Yes, a detailed VAT invoice is automatically generated and included with your delivery email. For B2B customers within the EU, the reverse-charge mechanism is applied where applicable.
We offer a fully secure, Stripe-powered checkout that accepts a wide range of payment methods, including credit and debit cards, SEPA bank transfers, iDEAL, BLIK, and Google Pay.
We offer a 14-day refund right in accordance with EU consumer protection regulations. If you have not activated or used the licence, you can request a full refund within this period.
During a SAM audit, you will be asked to prove that you have a sufficient number of CALs for the users accessing your servers. The official documentation provided by Lizensa serves as this proof of purchase and legal entitlement.
