When you resume a paused workflow, the workflow starts where it was paused. You can resume a paused workflow, but you cannot resume a stopped workflow.
To resume a paused workflow:
Select Tools > Workflow > Workflow Reporting
Tip: Alternately, you can select Tools > Workflow > My Workflows.
Select one or more workflows.
Select Tools > Workflow > Resume Workflow.
If prompted to confirm, click OK.
