Programatically download exported search results in ediscovery
are there any powershell commands or APIs to download the exported search results from protection.office.com -> Search & Investigation -> Content Search
You're supposed to use the application for that. There is a way to make it work by getting the ContainerURL and using tools such as AzCopy, but that's not supported in any way. If you still want to try it, do a search for a similar thread we had here a while back.
OK, since I'm in a generous mood today, here's the thread: https://techcommunity.microsoft.com/t5/Office-365/Export-to-PST-via-Powershell/td-p/95007
