You may be forced to use an Exchange Enterprise CAL if you customize an Active Sync / Mobile Device policy. These commands help you find how Exchange thinks you are licensed and how you can fix it.
# Collect license info $a1 = Get-ExchangeServerAccessLicenseUser -LicenseName "Exchange Server 2013 Standard CAL" $a2 = Get-ExchangeServerAccessLicenseUser -LicenseName "Exchange Server 2013 Enterprise CAL" #total standard licenses (even enterprise counts here) $a1.count #total enterprise licenses $a2.count #total standard only licenses $a1.count - $a2.count
Now take a look at what your mobile device polcy(ies) look like settings wise.
Get-MobileDeviceMailboxPolicy | select AllowBluetooth,AllowBrowser,AllowCamera,AllowConsumerEmail,AllowDesktopSync,AllowInternetSharing,AllowIrDA,AllowRemoteDesktop,AllowStorageCard,AllowTextMessaging,AllowUnsignedApplications,AllowUnsignedInstallationPackages,AllowWiFi,ApprovedApplicationList,UnapprovedInROMApplicationList
Set those settings back to the defaults (allowed) and it’ll take care of your licensing issues. But be warned that it could cause warnings or issues on any Active Sync users. You should test this with a new policy first before just changing the policy everyone is using.
