Release Tab and Delete Tab Locations
Either move the Release tab in Message Queue Quarantine (User_ and Quarantine (Admin) from beside the the Delete Tab or add a confirmation popup that states you are releasing selected emails for delivery.
Since the Release and Delete tabs are next to each other there have been several occasions that emails have been released for delivery instead of deleted.
A confirmation on the Release tab should be done regardless.
Thank you for sharing your idea to add a confirmation prompt to the release and delete buttons. It will be considered for future versions.
