How the Auto-label Policy for Cloudy Attachments Works
Cloudy attachments are links to files sent in messages. An auto-label policy can capture copies of cloudy attachments and make them available for eDiscovery. Sounds good, but you need Office 365 E5 or above licenses to use an auto-label policy and Purview eDiscovery (premium). Even so, it’s a nice example of applying technology to solve a problem, even if it does use up some valuable SharePoint Online storage quota.
