To activate Azure DevOps Basic on your enterprise tenant, you need to manually assign the Basic access level to users in your organization. Here are the steps you can follow:
- Sign in to your Azure DevOps organization at
https://dev.azure.com/{Your_Organization}. - Go to Organization settings by selecting the gear icon.
- Navigate to Billing.
- To add users, you can assign them the Basic access level when you add a new user to your organization.
- Remember that the first five users get Basic access for free, and after that, you will need to pay for additional users.
Additionally, if you have GitHub Enterprise users, they will be automatically detected and granted Basic access when they sign in using the same Microsoft Entra tenant.
For more detailed information, you can refer to the Azure DevOps documentation regarding user and permissions management.
