You may want to undo an archiving. For example, if a “dormant” client becomes active again. For this you have the “Unarchive” action.
Note, that this action will NOT turn on the monitoring automatically. Therefore, if you want to monitor the assessment, you will have to do it manually.
After unarchiving, the assessment’s status in the “Status” column will return to the one it had before archiving (“Completed”, “Pending” etc).
