Note: If you've deleted a group (Teams are based on groups), it will be retained for 30
days by default. This 30-day period is considered a "soft-delete" because you can
still restore the group. After 30 days, the group and its associated contents are
permanently deleted and cannot be restored.
Start a support ticket by using this link Request Help.
Provide name of team deleted.
Verify deleted date is not over 30 days.
Note: If not sure if it is over 30 days, still submit the ticket. Server Administration
team will perform a search for the Team and see if it is available to be restored.
Request support route ticket to Server Administration Team.
