discussion board auditing
When a discussion board item is deleted, there is currently no trace of the content in the recycle bin (to be restored), or the audit logs to show what was deleted.
The discussion board is a great feature in SharePoint Online that allows users to collaborate and share ideas as well as ask questions. However for most companies it can be an avenue of abuse via a somewhat public forum. It would bring a lot of confidence to roll this out more if there is the ability to find what was deleted in the audit logs. So that if a user was under HR investigation, data can be found.
