Exchange 2019: How Many CALs/SALs Do You Need?

KB ID 0001703

Problem

At his point I’m going to assume you know that there are Standard Exchange CALs/SALs, and Enterprise Exchange CALs/SALs. And you know the difference! If you’re unsure see my comments here.

With older versions of Exchange 2010/2007 etc. You could get this information from the GUI. Now you need to use some PowerShell.

Solution

The two commands you want to use are;

Find Out How Many Exchange Standard CALs / SALs Are Required

Get-ExchangeServerAccessLicenseUser -LicenseName (Get-ExchangeServerAccessLicense | ? {($_.UnitLabel -eq "CAL") -and ($_.LicenseName -like "*Standard*")}).licenseName | measure | select Count

Find Out How Many Exchange Enterprise CALs / SALs Are Required

Get-ExchangeServerAccessLicenseUser -LicenseName (Get-ExchangeServerAccessLicense | ? {($_.UnitLabel -eq "CAL") -and ($_.LicenseName -like "*Enterprise*")}).licenseName | measure | select Count

Sit back, light your pipe, and admire your handiwork!
