Okta Identity Engine
Okta Integration Network
Overview
This article explains why the following error occurs when attempting to provision licenses in Office 365:
License assignment failed because service plan A depends on the service plan(s) B
Applies To
- Office 365
- Provisioning
- Okta Integration Network (OIN)
- Okta Identity Engine (OIE)
Cause
The error indicates that Microsoft does not allow the assignment of license A because it is dependent on license B, which is missing from the user's license assignment. This is a Microsoft error, as Okta sends the request to Microsoft, and Microsoft rejects the license assignment due to a missing license dependency.
Solution
- Run the Microsoft PowerShell command to confirm the license dependency, as indicated by the error.
- Update the Okta application assignment or license assignment to include the missing dependent license.
- Retry the provisioning task.
- If additional details are needed, involve Microsoft support.
