If you still use the legacy Intune integration, the following points are important:
The legacy integration is different
It allowed connecting to devices using QuickSupport and required user acceptance.
It did not require the device to be a managed device in TeamViewer.
It allowed connections to devices that were not part of your TeamViewer device inventory.
This is no longer the case with the new integration.
The new integration requires managed devices
With the new Intune integration:
The remote device must be a managed device in TeamViewer.
Connections to bookmarked devices or unmanaged devices are no longer supported and will result in an error.
Retirement timeline
The legacy integration will be retired in April 2027.
We recommend migrating to the new integration as early as possible.
