Microsoft is planning to modify the Office 365 sign in process slightly by September 15th or October 1st and has kindly supplied advance notice and support for OnedriveMapper, but only for V3.29+ and V5.15+
For a basic scenario where users are unwilling or unable to navigate to the Onedrive folder in their profile, the following script will ensure all users on a given machine get their Onedrive profile folder mapped to the O: drive, it auto-installs as scheduled task at logon.
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.
