The end user can manage licenses through the Portal. Please note, users managing licenses via the self-service portal need to have Global Admin permissions in Office 365 AND EITHER ONE of the roles in CRM:
- Work 365 Administrator
- Work 365 Subscription Manager
Navigate to ‘Manage My Services’ ➤ ‘Manage Licenses’, this will display a list of licenses that are available in the end-users Office 365 environment.
The end-user can add licenses from here for other users. To do that simply click on ‘Manage License’ for a license, a right pane will open. Update the license for a user and click on ‘Submit’.
Note: You'll need to enable pop-up in your browser
The user will be assigned the license in Office 365 as well.
