Hi All,

I have a business customer with six W7-pro in a local
area workgroup. They live and die on a Outlook calendar
in a single computer. The customer asked me if I
could migrate the calendar into a workgroup calendar
that everyone could see and select individuals could
edit.

The calendar would need to

1) stick to the local area workgroup (no cloud service)

2) involve no Linux or Windows servers

3) open source in highly preferred (non proprietary)

4) does not use a browser for an interface


You guys have an tips?

Many thanks,

Two that I have used are Rainlendar Pro (free or paid) and its open
source and Linux / Windows compatible. I paid so I could get a
connection to Google calendar which is not in the free version. But if
you have a shared space on the network, both of these program provide
creating local .ICS ical files. With this one you get a desktop list
of events, a calendar and a todo list. All are optional to be displayed
on the wallpaper/desktop. I show the event list on my desktop down the
right side.

Also desktop calendar lite.

Again this can point to a shared folder/files someplace.

Both however are high on my list since I want the events showing on the
desktop. The calendars are optional. And both programs allow
customization. I've even tweaked the files for Rainlendar to make my
own size color shape wording etc for my event list. Took a few months
but I got it. Pure XML and png/jpg image files.
