Hello Paul McNamara,
Thank you for posting your question in the Microsoft Q&A forum.
As I am understanding the issue you are experiencing is disabled "Create" button in Azure AI Foundry when attempting to create an AI Hub resource typically indicates either UI-related limitations or backend configuration gaps, despite having sufficient quotas and permissions. Below are some steps you may take as a resolution approach to understand the root cause and resolve the issue:
Root Causes & Solutions
- UI-Specific Issues:
- Browser caching or temporary glitches may prevent the button from activating. Try clearing cache or using Azure CLI (az ai hub create) as an alternative.
- Microsoft has acknowledged occasional UI bugs in Foundry monitor Azure Status for outages (please check the page link provided below).
- Missing Prerequisites:
- AI Hub requires an existing AI Project in Foundry. Verify your project is properly initialized.
- Ensure your subscription is whitelisted for AI Hub features (contact support if unsure).
- Permission Conflicts: Cross-check both Azure RBAC (Azure AI Hub Contributor) and AI Studio roles (Project Admin).
