One of the things we have on our current website is a district calendar hosted on Google Calendar that aggregates individual school building calenders in to one district view(about 16 calendars in total at this point but if this works it may be more like 20). This doesn't work for reasons I won't get into right now but I'm trying to replace this with SharePoint 2010 calendars (and I hopefully won't have to code anything).
We want this to be very easy for the buildings to update so they should be able to subscribe to the calendar and (if they have access) update the calendar without having to leave Outlook. We also want to push this calendar out to all the staff at that building so they have access to it. We also want to have the district wide events (PDs, Holidays, breaks, etc.) be display in the building level calendars.
I've tried adding calendars to a view but that only allows ten calendars and doesn't get pulled into Outlook correctly. I tried creating a master calender using End User Sharepoint's screencast but while that displays properly on the web it doesn't get pulled into Outlook correctly.
Any help would be greatly appreciated.
