Activate or deactivate an alert
When you want to remove an alert completely for all domain users, you can delete it. However, it you want to stop an alert temporarily so that you can start it again in the future, you can deactivate it. This way, you can reactivate the alert when you want it to start running again.
To activate or deactivate an alert, go to Administration → Alerts Configuration → Alert Subscriptions. The filter works a little like the Finder in that the two lists are hierarchical. Select a category in the box on the left to view a list of its subcategories in the box on the right. Click All Categories to reset the filter.
As alerts are created and deleted over time, it's possible that a subcategory that was created in the past no longer contains any alerts. When this happens, Devo lets you know by displaying a Delete button when you hover over the subcategory in the filter list.
Once you locate the alert in the list, simply use the ON/OFF switch in its row to activate or deactivate the alert.
