EWS Requires the Proxy service installed

Important note: EWS only works if you have the Proxy role installed and properly configured. If not, you will not be able to use the EWS feature, as Outlook try to connects for the port 443, more information in the next Bugs:

Please make sure you have Proxy installed before you try to configure your Outlook Clients in OS X

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
