What are access licenses (CAL)?

Access licenses, also known as Client Access Licenses (CAL), are special licenses that allow users to access server services. These licenses are required when multiple users or devices want to access a server to ensure that the software is used legally. CALs are an important part of licensing for many Microsoft server products and help regulate and manage usage.

What types of access licenses are there?

There are two main types of access licenses: user CALs and device CALs. User CALs are intended for individual users who access the server from various devices. Device CALs, on the other hand, are intended for devices used by multiple users. The choice between these two types depends on the specific usage and requirements of your company.

How do I choose the right CAL for my company?

The choice of the right CAL depends on the number of users and devices in your company. If many employees work from different locations, user CALs may be the better choice. If, on the other hand, multiple users share a single device, device CALs are more sensible. A careful analysis of your usage patterns helps you determine the appropriate license type.

What should I consider when licensing?

When licensing access licenses, you should ensure that you correctly estimate the number of licenses needed. It is important to understand the license terms to avoid legal issues. Additionally, you should regularly check whether your licensing meets your company's current requirements, especially when there are changes in the number of employees or device usage.

• User CALs for individual user access
• Device CALs for multiple users on one device
• Regular review of license requirements

How do I acquire access licenses?

Access licenses can be purchased through authorized Microsoft resellers or directly from Microsoft. It is advisable to inform yourself about the various licensing options and packages before purchasing to find the best solution for your company. Be sure to check the license terms to ensure you acquire the correct number and type of licenses.

How do CALs differ from other licenses?

Access licenses differ from other license types because they are specifically designed for accessing server services. While other licenses may regulate the use of software on a single device, CALs focus on the authorization to access server resources. This makes them an essential part of server licensing and user access management.

What system requirements apply to CALs?

Access licenses themselves have no specific system requirements, as they are not software that needs to be installed. However, the servers being accessed must meet the corresponding hardware and software requirements. Ensure that your server environment meets the necessary prerequisites to guarantee smooth use of the CALs.
