Microsoft Exchange Server 2019 Device CAL

Microsoft Exchange Server 2019 Device CAL – license per device in a legally compliant way, keep an eye on costs.

The Microsoft Exchange Server 2019 Device CAL is the device-based access licence for on-premises environments. It is especially suitable when several people use the same device – for example at shift workstations, in meeting rooms or at terminal and warehouse PCs. Assigning per device keeps costs clear and makes licence management easier.

A CAL grants access rights to a correctly licensed Exchange Server 2019 and does not replace the server licence. As a version-specific perpetual licence, it can be used without a time limit; this gives you planning certainty and makes audit-proof documentation easier. The Device CAL is a sensible alternative to the User CAL when access is mainly through a few shared devices.

Features

• Device-based access licence: One CAL per device that accesses Exchange 2019.
• Designed for on-premises: For locally operated Exchange Server 2019 environments.
• Perpetual licence: Version-specific right of use with no time limit and no subscription.
• Cost-focused: Ideal for shared PCs and terminals.
• Licence-compliant: Supports clear, audit-proof documentation.
• Compatible with the Standard and Enterprise editions of Exchange 2019.
• No client software included: Outlook and other apps are licensed separately.
• Flexible licensing model: Device and User CALs can exist side by side in one environment.
• Downgrade access: Generally usable for older Exchange versions as well (in line with Microsoft guidelines).
• Language-independent: Suitable for international environments.

Benefits & value

With the Device CAL you license access to Exchange 2019 particularly economically where many employees use a few fixed computers. Clear assignment “per device” reduces administrative effort, makes proof easier and helps avoid over- or under-licensing. Thanks to the permanent right of use, investments can be planned reliably – independent of subscription cycles.

At the same time, your environment stays flexible: in areas with personal notebook or desktop use, a User CAL may be the better choice, while shared workstations benefit from Device CALs. This way you combine the right model for each scenario and keep your licensing situation in order.
