I want to change the default text presented to users in the calendar sharing dialog in Zimbra. Currently the default name for new shared Calendars is "<Users>'s Calendar". I wish to remove the "'s" from this string. I have attempted to alter definition of shareNameDefault in '/opt/zimbra/apache-tomcat-5.5.15/webapps/zimbra/WEB-INF/classes/msgs/ZmMsg.properties ' and restarted tomcat, however this had no effect. What file should I alter?
