Hello Akel Saleh ,
Based on the latest update, the issue appears to have resolved automatically without any changes made to permissions, pipelines, or environment configurations. For approximately two weeks, Environment Administrators were unable to access or deploy pipelines referencing environments and received the error:
"Encountered Error(s) while parsing pipeline YAML: Job XXXXX: Environment XXXXX could not be found. The environment does not exist or has not been authorized for use."
However, Project Administrators were able to deploy pipelines without issues during that time.
Since the behavior returned to normal without any action taken on our side, this was most likely caused by a transient service-side issue within Azure DevOps rather than a configuration or permission problem.
If anyone encounters similar behavior, we recommend:
Verifying environment security permissions under Pipelines → Environments → Security
Checking environment authorization for the pipeline
Reviewing Azure DevOps Service Health or retrying after some time in case of a temporary platform issue
Thank you for confirming that the issue is now resolved.
