Migrating OneDrive content for the same user with concurrent tasks is not recommended. OneDrive content for user (User@Domain) is being migrated with task (Task Id:s<TaskID>).
原因
The first task completed but failed to clean up its internally stored temporary task state due to an environmental issue or an intermittent platform problem.
対策
The message will be cleared in one of two ways:
Re-running the first task: If the task is rerun and completes successfully, it will correct the internal task state.
Automatic cleanup: After 7 days from the original task execution, the system will automatically correct the task state.
