A long journey’s end: Azure AD group-based licensing is now GA!
- Developer APIs in Microsoft Graph to allow you to programmatically read group-based licensing assignments on groups, as well as programmatically get assignment status and errors.
- Ability to reprocess group-based licensing assignments for a single user.
- Simplified licensing requirements for group-based licensing. Users who are targeted for group-based licensing need Azure Active Directory (Azure AD) Basic (and above), or Office 365 E3/A3 (and above).
So you need at least any paid Azure AD license to use GBL.
To start using group-based licensing, look at our Assign licenses to users by group membership in Azure AD documentation
