Scenario, a user who is a Team owner, had created Forms in their group. Without knowing what would happen they deleted the team. Approximately 45 days passed before they found the issue. The Team/Group had already been purged after 30 days, however the Sharepoint data had not yet purged. I created a new group, with the same original name, and restored the data to connect to the new group.
The old Forms seems to still be worked and the user would like to deactivate them, however, nobody can find the old Forms to do this?
