FAQ: Exchange Server 2016 Standard -- 1 User CAL
1. What is Exchange Server 2016 Standard -- 1 User CAL?
Exchange Server 2016 Standard -- 1 User CAL is a Client Access License assigned to one user. It is not a program to be installed or a separate server, but a licensing document that authorises a specific person to legally use the services of the Microsoft Exchange Server 2016 Standard environment. Such a licence is required when a user is to use the company email, calendar, contacts, or other features provided by the Exchange server.
In practice, this means that the Exchange server licence alone is not enough. In addition to it, appropriate access licences (CAL) are also needed for users or devices that will connect to the server.
2. What exactly does CAL mean and why is it not "ordinary software"?
CAL, or Client Access License, is a licence that authorises access to Microsoft server services. In the case of Exchange, you do not buy an additional application that is installed on an employee's computer. You buy the right to access in accordance with the manufacturer's licensing terms.
This is very important from the point of view of compliance. The client receives a legal licensing entitlement, not a new medium, disc, or independent program. Therefore, this product should be treated as an element of licensing documentation and compliant use of IT infrastructure, not as a standalone installation tool.
3. How does User CAL differ from Device CAL?
User CAL is assigned to a specific user. This person can use Exchange from multiple devices, such as a desktop computer, laptop, phone, and tablet. This solution is cost-effective when one employee uses email on several devices.
Device CAL is assigned to one device. Multiple users can use such a workstation, but the device itself remains covered by one access licence. This model is more common in shift environments, reception points, warehouses, or wherever several people work on a shared computer.
If the company has mobile employees, User CAL is usually a better choice. If, on the other hand, several people use one terminal or workstation, Device CAL may be more economical.
4. How many Exchange User CAL licences do I need to buy?
The rule is simple: you should have as many User CAL licences as there are users who actually access the Exchange server. If 8 employees use the company email, 8 User CAL licences are needed. If a ninth person joins, another licence must be purchased.
It does not matter if the user logs in every day or sporadically. What counts is the entitlement to access. That is why, when planning licences, you should consider not only the current team but also technical accounts, remote workers, management, and people using email on mobile devices.
5. Can one User CAL licence be shared among employees?
No. User CAL is assigned to one person and should not be rotated among different users just to reduce costs. Such a practice may be considered a violation of the licensing terms.
If the company has several employees who use one computer alternately, instead of a "shared" User CAL, it is worth considering the Device CAL model. The choice of licence type should reflect the actual work method, as compliance with the actual state is crucial during an audit or inspection.
6. What about licence compliance and potential audits?
In the event of an audit, the manufacturer or an authorised entity may expect proof that the number of users or devices with access to Exchange corresponds to the CAL licences held. The company should therefore keep purchase documents, licensing data, and internal records of users covered by access.
The most common problems arise when the company develops faster than its licensing documentation. New employees are hired, new mailboxes are created, or email is made available on phones, but the number of CALs is not updated. Regular licence reviews help avoid shortages, additional payments, and unnecessary legal risks during inspections.
7. Is this key and licence legal, and how is their authenticity verified?
The legality of the product should be confirmed by full sales and licensing documentation. The key or licensing entitlement must come from a legitimate source and be intended for further, lawful distribution. For the client, the most important things are: a clear product description, proof of purchase, correct licence specification, and the ability to document the origin if needed.
At KluczeSoft.pl, the client receives a licence intended for legalising access, not a random code without documentation. This is particularly important for companies, offices, and accounting firms that must demonstrate IT purchase compliance in their accounting and organisational documentation.
8. What does the licence delivery look like, and what do I actually receive after purchase?
The delivery is electronic. The client receives a set of information necessary to confirm the purchase of the licence and its application in the company environment. Since this is a licensing product, not boxed software, the standard is digital delivery, without a physical medium.
This solution speeds up order processing, simplifies document archiving, and allows for faster completion of licensing gaps, for example, before deploying a new employee or before an internal compliance check.
9. Will I receive a VAT invoice?
Yes, the purchase of a licence for a company should be confirmed by a VAT invoice, which is a basic accounting document and one of the important elements confirming legal purchase. The VAT invoice is important not only for settlements but also for documentary order in the event of an audit.
It is worth keeping the VAT invoice along with information about the type of licence, the number of CALs purchased, and their assignment to users or devices. Such a set of documents significantly simplifies later verification of compliance.
10. Can the User CAL licence be transferred or reassigned to another person?
The possibility of transferring the licence depends on the licensing rules applicable to the given distribution model and on whether the change is permanent or temporary. As a rule, the assignment should reflect the actual use of the system, not serve to circumvent the requirement to purchase the appropriate number of CALs.
If an employee leaves the company and their account is permanently deleted, it is usually possible to analyse the possibility of assigning the licence to a new person in accordance with the applicable terms. In case of doubts, it is best to consult a specific scenario before purchase or before changing the records.
