IBM Notes Traveler and "iCal embedded" Calendar Entries
I had the issue, that appointments from an IBM Connections Community, which are embedded via an iCal link are not getting synched to a mobile device.
After opened a PMR I received a fix for IBM Notes Traveler 9.0.1 IF7 where those appointments also are synchronized to the mobile device.
So if you use the iCal feature for e.g. Community appointments you should open a PMR and reference to PMR 78198,010,618.
