On many (but not all) team sites, the team discussion gets the following Error.
Error Cannot complete this action. Please try again. Troubleshoot issues with Microsoft SharePoint Foundation. Correlation ID: c07efd14-f3cf-45a6-bb3c-e42ea5f40590
How can I troubleshoot this or what is the likely cause?
The sites that this is still functional appear to have empty discussions. But can create and use new team discussions.
