On the Manual task tab, text that follows the label Connected to Universal Contact Server displays information about the status of the task that is running. This information can be any of the following:
Manual Pruning main initializing
Manual Pruning main running
Manual Pruning main done
Manual Pruning main failed
Manual Pruning archive initializing
Manual Pruning archive running
Manual Pruning archive done
Manual Pruning archive failed
Manual Archiving initializing
Manual Archiving running
Manual Archiving done
Manual Archiving failed
Scheduled Pruning main initializing
Scheduled Pruning main running
Scheduled Pruning archive initializing
Scheduled Pruning archive running
Scheduled Archiving initializing
Scheduled Archiving running
Most of this is self-explanatory, but note that failed means that initialization of the task has failed.
