Does anyone else find Azure access problems harder to diagnose than the underlying issue? The resource exists and appears to be configured correctly, but one person can perform an action while another person cannot. I usually end up checking role assignments, inheritance, scope, policies, and other settings across several levels. What process or tools do you use to identify the exact cause without manually inspecting every setting?

Read the complete error message first. It often points directly to the cause, such as a missing role assignment, a service principal without access, or an Azure Policy denying the operation. The wording usually tells you whether to investigate RBAC, policy, or the resource configuration.
Inherited deny assignments are easy to miss, especially when they come from a management group several levels above the subscription. If someone has an apparently sufficient role like Contributor but still can’t create a resource, check effective access and the higher-level management group settings.
A useful troubleshooting approach is to compare the working user and the affected user. Pull their role assignments with the CLI or Resource Graph, compare group membership and scopes, and then check for deny assignments or policy effects. That is usually faster than clicking through every portal blade.
For Azure IAM issues, start by checking effective permissions on the affected resource or resource group. If that doesn’t explain it, work backward through the assignment scopes—resource, resource group, subscription, and management group—to find inherited roles or restrictions. Azure Resource Graph can also help you query authorization resources and see who has access across the environment.
RBAC gets especially difficult at scale. Keeping assignments scoped to the smallest practical level and regularly cleaning up old roles helps prevent the inherited-permission spaghetti.
