EWS Requires A License Key

To see if your ZCS server has EWS enabled, you must check from the CLI - see bugs noted below. This is also true for the "Touch client". If you want these features and currently don't have them as a part of your license, please contact your sales agent so you can get a new license issued with these features enabled.

$ zmlicense -p | egrep -i 'touch|ews'
EwsAccountsLimit=10000
TouchClientsAccountsLimit=10000

If you needed to get a new license, you should either do the following on your ZCS server or those running the mailstore services, after installing the license to get EWS working:

zmprov fc license

Or a full zcs restart :

zmcontrol restart
