Before you can authorize ArcGIS Pro Named User licenses, you must activate your ArcGIS Online subscription and set up your ArcGIS Online organization. These tasks should be completed by software license administrators. This topic is a short overview with links to detailed topics in the ArcGIS Online help.
Activate your subscription
To begin, click the activation link in the email you received from Esri Customer Service. Next, follow the steps in the ArcGIS Online help to activate your subscription. If you can’t find the email with the activation link, contact Customer Service for assistance.
The person who activates the subscription automatically becomes the administrator of the ArcGIS Online organization. If you do not intend to be the administrator, forward the email to the appropriate person.
Add members to your organization
After you set up your organization, you can invite and add members as described in the ArcGIS Online help.
You can assign ArcGIS Pro licenses and compatible user types when you add members, or you can do so later.
