You can sync events, tasks and notes from independent calendars to SyncML-Services. If these services provide more than one calendar you also can sync to multiple calendars on the server side.
Thanks jukey. I could read it in German - I'm from Vienna :-)
It looks like I'll try to get a syncML service with multiple calendars which also syncs to Thunderbird/Lighting.
Inbetween I'll try Erminig-NG: http://talk.maemo.org/showthread.php?t=40408
It syncs to google with multiple calendars. It's available since yesterday and I'll definitely try it (after a backup of the cals :-)
Not sure if I should ask this here, but My Cal no longer syncs. If I go into Mail for exchange and click on "Full resynchronization" The Gui shows theinitializing works, but when it gets to the Cal and Tasks it hangs at about 98%. If I do contacts by its self it works. So as of now the Cal is messed up. Is there something I can delete? or a log somewhere I can look at?
If you're having trouble importing iCal .ics files to the N900 calendar, you should know that the alternative GPE Calendar app handles the import fine. I have detailed instructions for using GPE Calendar as a clean-up converter on my blog. Basically, install GPE Calendar, have it import the .ics file, run the command line command gpe-calendar -e filename.ics and open that in File Manager to get your events correctly imported into Maemo Calendar.
importing ical by clicking it is ok but tiring.
I wrote this script to do this automatically. http://talk.maemo.org/showthread.php?t=61203
