We recently added the ability to transfer ownership to another user when deleting a user’s account from AAD from the M365 admin portal. If no entry is provided, the default will transfer to the manager. https://docs.microsoft.com/en-us/onedrive/retention-and-deletion
The manager or newly assigned owner will have the ability to sync that content or download and then move to a shared library or their own OneDrive.SGingerich supported this idea ·SGingerich commented
IT admins need the ability to transfer ownership of OneDrive docs from one user to another easily where the new account takes over, ownership changes and the files are not automatically deleted in 30 days.
I have users that are not computer savvy at all and they get confused as to how to access their own account let alone trying to access, download to move account files elsewhere.
