Answer 1

Deleting a team project permanently removes data associated with that project from the database. You cannot recover it later.

1. Open the administration context for the team project collection by choosing the gear icon.

2. Open the .... menu for the team project that you want to delete.

3. You must type the name of the team project in order to initiate the delete operation.
