Is there a way to link a web schedule to and exchange account?
You would need to implement your own custom WebSchedule data provider to read from and write to Exchange.
Infragistics currently does not have a WebSchedule data provider to communicate with Exchange. You can submit a feature request if you'd like to see this in a future release of the toolset.
Somewhere around here there is some code on how to use a customdataprovider for webschedule, take that code and covert it to use ADO instead of what ever it is using (if it is mine then it is using SQL)...
Then just connect to exchange via ado and pull the calendars, your users will have to enable sharing of calendars but that is pretty much about it.
Any chance you know where I may find that code?
Tom Puglisi has an excelent article on this for the custom web schedule stuff you can access it here.

Here is a example calendar using ADO for exchange it isn't using IG but what he is doing will work for you as far as hooking up to exchange.http://www.codeproject.com/KB/aspnet/teamcalendar.aspx
