Decisions allows you to grant access to specific Office 365 Groups.
Control the usage of Decisions in your organization with permissions set at the Office 365 Group level. The first time you enable group-based license management, Decisions will automatically be enabled for all groups using Decisions to avoid any interruptions in access.
Below are the steps to enable or disable Decisions for a specific Office 365 Group.
Open the Decisions admin portal.
Follow the steps in the admin portal to enable group-based licensing.
If you do not have access, contact Decisions support. By default, the person who performed the Office 365 Admin Consent is listed as the account owner.
You can now enable/disable Decisions by Office 365 Group.
Go to the menu at the top to verify the list of Group admins is correct.
On the "manage admin" page, also verify the license request emails are correct. This is the person (or persons) who will receive email requests for new Decisions licenses.
You may want to enter an email address for existing license request systems you have in place.
Now, when someone tries to use Decisions in an Office 365 Group/Microsoft Teams team where it is not enabled, they will be stopped and notified they are missing a license. They will be given an option to open a draft email with the pre-defined recipient(s) you list above. The email includes a direct link to the admin portal so they can request a license from the appropriate admin.
Alternatively, you can also control usage through Azure AD, which requires individual users to be granted access, rather than everyone in the Office 365 Group. Note that this can be challenging to manage if you have frequent changes to the list of members or you want to invite guests to meetings.
