There is no difference in the installer for Xeams Community and Enterprise Edition. It will run as if you have purchased the Enterprise Edition for the first 30 days. It will then get converted to Community Edition unless a license is purchased.
I have the problem in my installation that users cannot see any emails using the search (Web-GUI)
Does this have to be set in the configuration?
As an admin this is no problem.
User messages are displayed in the main menu.
