Been trying to create an exchange replacement for years, for Outlook users :) Anyway, for Calendaring I came across an Outlook plugin that works with iCalendar (SourceForge: RemoteCalendars) Haven't tried it yet ... So ... went looking for an iCalendar 'server' and found WebCalendar (also on SourceForge) Does anyone have any experience with either of these or other such tools and have recommendations? (Don't mention Zimbra - the OpenSource version is effectively crippled - the Outlook Connector apparently isn't available with the OSS version - even though the full Zimbra version relies heavily on other OpenSource software: e.g. PostFix and OpenLDAP) I noticed someone posted a question about iCal on the 1st of August and got no response at all ... but maybe someone has actually setup a linux box to use iCalendars somewhere ... ? -Thanks for any information you may be able to supply
