I have been trying to migrate from our team shared calendar in Exchange and move over to SharePoint 2010 for our permanent Team Calendar. However, we have an On Call event that re-occurs and has a different user on call every week. The duration is the entire week. When attempting to put this in SharePoint, the option to set the duration to longer than 24 hours disappears.
Am I missing something here? Can I create a custom list calendar and fix this? This is the last thing that is keeping us from using SharePoint exclusively for our team calendar.
