For a customer case/project, we wanted to move only recently synced/modified Sharepoint Online data from Tenant A to the user’s Desktop on the device itself.

The Desktop was synced to Onedrive for Business in Tenant B.

After copying, files from Tenant A should become read-only on the local device, and the link in Explorer to Tenant A’s sharepoint should be removed, including the actual onedrive sync relationship to prevent further ul/dl’s.

Resulting in https://gitlab.com/Lieben/assortedFunctions/-/blob/master/migrate-modifiedSpOSyncedFilesToUserDesktop.ps1
