Sometimes a Team is no longer needed at some point. Perhaps it was for seasonal work, and you need to deactivate the Team to make it easier to work without it appearing in the lists. We don't delete Teams, as they are usually associated with entire event chains, task completions in the past, and other dependencies. Therefore, to ensure you can always obtain accurate reports from the past, Teams cannot be deleted. We simply deactivate them and remove them from the interfaces.
To deactivate a team profile, click the three dots button on the right side of its status and choose "DISABLE" from the dropdown menu.
