I created a case queue for our finance department. When I save under admin/inbound email settings, I get an error (No optimums were saved with your Inbound Email account. Please review the settings) and it will not save port 993 and SSL yes. I checked all email + sugar settings but I cannot pinpoint what the cause of the problem is. Our other case queues are set up in the same way and the new case queue is a duplicate of the active/working case queue.
Working on Sugar Version 6.7.11 (Build 1053)
