Buy Exchange Server CALs – Access Licences for Microsoft Exchange Server
Exchange Server CALs (Client Access Licences) are access licences required to enable users to access the features of a Microsoft Exchange Server. They form a central component of Exchange Server licensing and enable organisations to operate their email and communications infrastructure in a legally compliant manner.
Whilst the Exchange Server licence itself permits the installation and operation of the mail server, CALs govern users’ access to mailboxes and Exchange services. Organisations therefore require, in addition to the server licence, the appropriate access licences for all users who send and receive emails or use other Exchange features.
Exchange Server CALs are typically used in corporate environments where a central mail server is used for internal and external communication. They enable staff to access emails, calendars, contacts and other features via applications such as Microsoft Outlook or Outlook Web App.
Typical use cases for Exchange Server CALs include, for example:
- Access to corporate email accounts
- Managing calendars and appointments
- Use of contacts and tasks
- Access to shared mailboxes and team communication
- Integration with Outlook and mobile devices
The Exchange Server CAL licensing model allows organisations to flexibly adapt their mail server infrastructure to the number of users within their organisation.
Types of Exchange Server CALs
Microsoft offers two different types of Exchange Server access licences.
Exchange Server Standard CAL
The Standard CAL provides the basic functions of Exchange Server. It enables users to access email inboxes, calendars, contacts and tasks.
The key features of the Standard CAL include:
- Email communication via Exchange Server
- Calendar and appointment management
- Contact management
- Access via Microsoft Outlook and Outlook Web App
- Use of mobile devices
This licence is suitable for organisations that use Exchange Server primarily for traditional email and communication functions.
Exchange Server Enterprise CAL
The Enterprise CAL extends the functionality of the Standard CAL with additional features for archiving, compliance and data management.
Typical features of the Enterprise CAL include:
- Email archiving
- advanced compliance functions
- eDiscovery and legal retention
- Data Loss Prevention (DLP)
The Enterprise CAL is frequently used in larger organisations where there are advanced data management and compliance requirements.
Exchange Server CAL versions
Exchange Server CALs are version-specific and must always match the version of Exchange Server being used.
Typical CAL versions are:
- Exchange Server 2019 CAL – access licences for Exchange Server 2019 environments
- Exchange Server SE CAL – Access licences for the current Exchange Server Subscription Edition
As a general rule, newer CAL versions can often be used for older Exchange Server versions, whilst older CALs are not valid for newer server versions.
When do I need Exchange Server CALs?
Exchange Server CALs are required whenever users access the features of an Exchange Server.
Typical scenarios include, for example:
- Access to corporate mailboxes
- Using Outlook or Outlook Web App
- Access to shared calendars
- Using contacts and tasks
- Access to mobile email services
A corresponding access licence is required for every user who accesses the Exchange Server.
Exchange Server CAL vs Microsoft 365 licence
Many organisations compare Exchange Server CALs with Microsoft 365 licences. Both models enable the use of email services, but differ in their deployment model.
Exchange Server CAL (on-premises)
The email infrastructure is operated in-house. The data remains on local servers within the organisation’s own IT environment.
Microsoft 365 (Cloud)
The email services are provisioned entirely via the Microsoft Cloud.
Exchange Server CALs are particularly suitable for organisations that operate their email infrastructure on-premises or wish to use hybrid environments with Exchange Server and Microsoft 365.
