We can install the trial version for you on your server. Click the "Live Chat" button at the bottom of this page to set up a remote control session to your server. The installation and configuration takes 15 minutes.  

Please note.. this software is a plug-in (add-on) for Exchange server. It does not work without Exchange server.
If you don't have an Exchange server you might be interested in the Outlook client version.

 

Installing the fully functional 30 days trial version onto your Exchange Server is a zero risk operation. It will not add or replace system components and will not impact the service pack level or post-fix updates  performed in the past. The setup will only create a new folder and place two files on the server but Exchange Server does the work...as it was designed to do!
Exchange GroupCalendar works without an external (sql) database or other external technology.  It's a purely Exchange server based tool using its full potential without installing potentially damaging dll's or replacing any sytem components.

Please remember that you can call or email at any time if things are not clear or working as expected.
