New Exchange License Cmdlets

We all know the old script to count the Client Access Licenses [CALs] in Exchange 2010 was never 100% accurate... With Exchange 2013, two new cmdlets were introduced: Get-ExchangeServerAccessLicense and Get-ExchangeServerAccessLicenseUser.

Get-ExchangeServerAccessLicense

This cmdlet returns a list of licenses in use in an Exchange 2013 organization, with the legal name of the license as defined in the Microsoft Product List.

If, for example, you want to check all the licenses in your organization, simply run the following cmdlet:

Get-ExchangeServerAccessLicense

The possible license names are:

  • Exchange 15 Standard CAL
  • Exchange 15 Enterprise CAL
  • Exchange 15 Server Standard Edition
  • Exchange 15 Enterprise Edition

Get-ExchangeServerAccessLicenseUser

This cmdlet, on the other hand, returns a list of unique users (their fully qualified domain name [FQDN] or primary SMTP address) representing an estimate of the licenses required when it is run.

To check how many users need a Standard CAL, for example, you run the following cmdlet:

Get-ExchangeServerAccessLicenseUser -LicenseName “Exchange Server 15 Standard CAL”
