If your Microsoft Endpoint Manager integration was connected before April of 2023, it still relies on the enroll by user field to assign an owner to the device on Vanta. In April, we released an update that allows the primary user field to be used, and administrators will need to reconnect their existing connection to take advantage of this (if they desire).
Prerequisites
Administrator access to Vanta
An Azure AD Account with one of the following roles: Global Administrator, Cloud Application Administrator, Application Administrator, or owner of the service principal.
Procedure
Sign into Azure and then search for Enterprise Applications:
You would then search for Vanta Intune in the search box for applications and click on your Vanta Intune application
From here, click properties
Then delete it
Once deleted, you can go to the integrations page on Vanta, click Manage, then Edit under Microsoft Endpoint Manager
Click connect Microsoft Endpoint Manager and re-follow
You will be taken to a window where you will sign into Microsoft Endpoint Manager using your Microsoft account and then be re-directed to this window where you need to accept the permissions to install the updated app
Once this is done, the integration should be re-connected, and devices on the inventory page will be assigned an owner using the primary user field.
