Microsoft Exchange Server Enterprise CAL 2019 is a software product that provides access to the features and functionality of Microsoft Exchange Server. It is an additional license to Microsoft Exchange Server Standard CAL. The license allows devices such as workstations, laptops, and mobile devices to connect to an Exchange Server and use its features.

For further questions about the product, please contact our customer service.


Enterprise User CALs for Microsoft Exchange Server 2019 as used software

For the Standard and Enterprise editions of Microsoft Exchange Server 2019, each user who wants to access the server services requires a separate client access license in addition to the server license: the Exchange Server 2019 User CAL. This alone equips a specific registered person with the appropriate access rights.

This is because, according to the terms defined in Microsoft License Management, a license for Exchange Server 2019 Standard or Enterprise no further user rights are included, so that these must be acquired additionally in the form of a User CAL. Registered users can thus use all Exchange Server functions via an end device of their choice.

Used User CALs for Exchange Server 2019 Standard and Enterprise Edition are available from Wiresoft not only at a favorable price, but also individually in customized quantities. Used User CALs offer the same functionalities as the User Client Access Licenses offered as new in the official Microsoft Volume Licensing Program for Exchange Server 2019.

Benefit from all new features of MS Exchange Server 2019 with used User CALs

Windows Exchange Server 2019 also runs on Windows Server 2019 Core and provides a reliable and secure platform for enterprise messaging infrastructures. The individual Exchange editions, such as Standard and Enterprise, offer all the functionalities to support not only comprehensive communication but also collaboration with a focus. Among other things, the following new functions and features are available for this purpose:

  • Meta Cache Database (MCDB) is used to save meta information such as folder structures of mailboxes and also to speed up access and search for content.
  • Dynamic Database Cache (DDC) increases the speed of Exchange Server and offers better use of storage capacity by dynamically adapting to current requirements.
  • The search index now resides in the database of a mailbox, simplifying management and increasing search speed.
  • Windows Server Core also allows simplified execution of the standard version of the server system, making configuration easier and providing more security against intruders.
  • With Client Access Rules, further possibilities are available in limiting access to the configuration area of Exchange Server.
  • Collaboration on documents is significantly improved with the option to make files available on OneDrive for Business.
  • New calendar enhancements make it easier to organize meetings: for example, with Improved Calendar Management, features such as Default End Date, Do Not Forward, and different options for configuring out-of-office messages.

User CALs for Exchange Server Standard- and Enterprise-Edition 2019 as used software - the most important at a glance

User CALs offered by Wiresoft as used software are no different from new products, they have the same access options as new products to use the features available in Exchange Server 2019 editions Standard and Enterprise. Therefore, used User CALs are a more affordable way to provide employees with an Exchange Server access license, especially for small and mid-sized companies and organizations, and it also allows for customized licensing.

General information about Microsoft license management of Exchange Server 2019 with CALs

For the Standard and Enterprise editions of Exchange Server 2019, Microsoft License Management is used to regulate the supplementary licensing of users with access rights so that employees can access e-mails etc.. This is because the CALs included in the server license are exclusively for IT administrators and may not be used for Exchange typical services. Only the client access license for User CAL gives an employee the rights to use Exchange Server functions - on any Windows-enabled end device. The User CAL does not include any software other than personal access rights to the Exchange Server 2019 client/server environment.

What are the benefits of User CALs for Exchange Server 2019 Standard- and Enterprise- editions?

CAL-based licensing for the Standard- and Enterprise-edition of Exchange Server 2019 enables accurate, on-demand management of access rights for all employees in an organization. The Microsoft licensing model offers two types of CALs for Exchange Server 2019 for this purpose:

  • User CAL for Exchange Server 2019 - valid for one dedicated user at a time
  • Device CAL for Exchange Server 2019 - applies to one dedicated end device (PC, laptop, tablet, phone) server access rights each

What are the differences between User CALs and Device CALs for Exchange Server 2019?

The User CAL for Exchange Server 2019 offers the same usage options as the Device CAL. However, the difference lies in the respective options for accessing the Exchange Server, which results in different benefits. In addition to the number of employees in a company and the equipment of their workstations with a PC or similar, the workflow in which the users access the Exchange Server also plays a role: In some SMBs, users may access it from completely different endpoints, while in another work environment, multiple employees may share a single endpoint and thus take turns accessing the Exchange Server to call in emails, etc.

Each individual employee authorized to access User CAL can therefore use any Windows-enabled end device to access Exchange services. This makes it possible to access the Exchange Server locally and independently either with one's own mobile computer or smartphone - e.g. while on the road or in the home office - but above all with any other device available on site via Internet access.

The User CAL therefore offers good mobile usage options, since the licensed user is not restricted in his choice of access - always provided that the end device used is Windows-capable.

Difference in the usage options of CALs for Exchange Server 2019 for the editions Standard and Enterprise

The editions Standard and Enterprise for MS Exchange Server 2019 differ, apart from functional enhancements at Enterprise, primarily in the scalability of the respective mailbox requirements. In principle, however, it is also possible to use the Enterprise edition with a User CAL for the Standard edition - however, not only the limited functionality of the Standard edition is then available, but also a correspondingly smaller number of mailbox databases. User CALs for the Enterprise Edition therefore offer a greater range of functions, provided that the Enterprise server license is installed.

Ensure version compatibility of User CALs for Exchange Server 2019

In addition to the above-mentioned options depending on the edition, the User CAL for one of the Exchange Server 2019 editions not only equips a user with the access rights for this exact server version, but also includes the access rights for older Exchange versions such as 2016 (downgrade). Thus, the User CAL of the server version 2019 offers an advantage over User CALs of older versions, which can also be used to access previous versions of Exchange Server, but not the Exchange Server version 2019 (upgrade).

The User CAL for Exchange Server version 2019 is the highest currently available, but in addition to the edition-specific functionality included, attention should always be paid to the compatibility of the server license and client access license.

What should you consider when licensing Exchange Server 2019 with a User CAL?

As mentioned above, a used User CAL license equips a single user with access rights to Exchange Server 2019. Once the user's registration is complete, this User CAL cannot be transferred to another person. Likewise, this precludes changing the CAL type and using the User CAL as Device CAL.

These restrictions in the Microsoft license management serve to prevent any improper access to the Exchange Server 2019 services. They thus provide greater security for a company and its communications, as strangers or unlicensed individuals do not have access rights to use the email services and other server data.

Conclusion on User CALs for Exchange Server 2019

So, which type of client access license for Windows Exchange Server 2019 offers more advantages in use in a company differs from case to case. Here, above all, the predominant type of access via existing end devices plays a decisive role: as soon as employees regularly alternate between using mobile end devices or various standalone devices, e.g. at different workstations, to access the Windows Server, the personal User CAL offers more advantages, because they can always use their personal account for this purpose.

Whether licensing with User CALs for Exchange Server 2019 is more favorable for a company than with Device CALs, because fewer licenses are then required, therefore results from the typical company workflow. Knowledge of this forms the optimal basis for the choice of CAL when purchasing used client access licenses for Exchange Server 2019.

User CALs for Microsoft Exchange Server 2019 available from a single license in the Wiresoft online store

User CALs for Exchange Server 2019 are available in Wiresoft Online Shop already from a single client access license - because possible volume license provisions of Microsoft are not valid after marking as "used", otherwise there are no disadvantages associated with usability - not only because a software cannot wear out in principle.

Origin of the User CALs for Exchange Server 2019 as used software at Wiresoft

These User CALs for Exchange Server 2019 offered by Wiresoft as used software are original licenses, as they are otherwise offered within the Microsoft licensing program; the difference is that the User CALs from Wiresoft used to be part of a volume license for Exchange Server 2019 for users that a company once purchased as a previous owner. The complete user volume license or even individual user access licenses were resold by the latter to Wiresoft, whereby the volume licenses were also broken down into individual licenses. These resulting individual User CALs are then labeled as used software. Nevertheless, despite this labeling as used licenses, they can be used like a new license to access the services of Exchange Server 2019, because they do not differ from these by restrictions in functionality or in their useful life.

Buyer assurance with User CALs for Exchange Server 2019 as used software

User CALs for Exchange Server 2019 offered by Wiresoft as used software are not only a low-cost form of licensing for Exchange Server 2019 for our customers, but their use is also safe and legal! These Wiresoft User CALs therefore also offer you as a customer the otherwise usual buyer security with immediate download after your purchase including immediate license activation via valid volume license key.

Is it legal to buy and use used User CALs for Exchange Server 2019?

Both User CALs that you can purchase from Wiresoft for Exchange Server 2019, as well as all other client access licenses offered in the store, come from corporate license inventories. Therefore, both the sale and the purchase of used CALs are based on the valid case law that explicitly allows the trade of Microsoft used licenses, which has also been clearly confirmed again and again by various court rulings.

This means that you as a buyer of used User CALs for Exchange Server 2019 and also as a user have legal security, since neither Wiresoft nor you are violating any legal provisions in the process.
