To delete the protected cabinet, you first need to request the unprotection.
In the upper-right corner, select your name>Admin>Repository name>Request cabinet unprotection.
In the pop-up window, select Proceed.
Now, you unprotected the cabinet and can delete it.
Note: If you are not the only administrator, your request sends a notification to all repository and cabinet administrators. Unless at least 2 more administrators approve it within 10 days, the cabinet remains protected.
To cancel the unprotection request, select Unprotection request pending, and then select Yes.
