If you originally assigned licenses to everyone in your organization, you can change the licensing to only a specific group within in your organization. Using Group Filters is the most effective way to manage your Cloud App Security licenses for a specific subset of users within your organization.
After changing to group licensing, or adding or removing users in a Office 365 and Microsoft 365 group, synchronization of the licensed users between the cloud application and Cloud App Security may require up to 24 hours.
To change to group licensing
Enter the name of the group to which you want to assign the licenses.
Only one group is supported for Office 365 and Microsoft 365 cloud applications at this time. If you enter the name of more than one group, an error message is displayed.
