I am using SharePoint Online and have a large list exceeding 50K items. When attempting to create an index I receive the error that the list exceeds the list view threshold. The solution to this appears to be creating the index during the 'Daily Time Window', which I cannot access in SharePoint Online b/c MSFT hides the 'Manage Web Applications' tool.
Is there a Daily Time Window for SP Online? If not, how can you create an index on a large list otherwise? Does anyone have experience with this issue in SP Online specifically?
