Running a discovery task generates an error: “UserPrincipalName not found for Tenant XXXXXX.onmicrosoft.com. Provide an active UserPrincipalName through Configure Connections.”
原因
Incorrect Username has been configured during the project setup, and the API requests are rejected as the configured Username is not registered in the intended Tenant.
対策
Under Projects > Accounts > Dashboard > Configure Connections >
check that the Tenants have the correct Username listed here. Update it, and save.
