When I open recurring events (DispForm.aspx) I'm getting the pesky "The attempted operation is prohibited because it exceeds the list view threshold enforced by the administrator". Calendar views with indexes work fine. There's over 20000 items in the list.
I understand the threshold mechanism, but I'm unsure why a recurring event is triggering the threshold error, specifically on the DispForm. The page doesn't have any lookups or additional webparts to anything.
Is there any way around this? Can you have more than "x" recurring event items in a given list or does the recurrence cause any query to that single item to trigger the threshold limit?
