Up until now it was almost impossible to get a good overview of your co-worker calendars and appointments integrated with Outlook. GroupCalendar is an easy to install Outlook add-on, which solves that problem effectively and flexibly. In addition to allowing group viewing of calendars, GroupCalendar also allows you to create and edit appointments on behalf of others. All of these features are available using nothing more then a peer to peer network or LAN - no server software is required.
This software is a commercial software. You will be able to download and test GroupCalendar during a certain period of time, then, if it does what you need, you will have to acquire the full version from GroupCalendar publisher. The GroupCalendar 1.6.85 free trial version contains an installer and an uninstaller, and has a size of 4782 Kilobytes.
For additional information and support request, please contact directly GroupCalendar publisher.
