Have you recognized that the message list in the outbox is sorted?
First all unread messages, then all read messages?
Shall we bet on that the missing message is still in your outbox?
Ahhh, that was the issue! They are all faaaaaar away with the other read messages! Ok, it is working ok. I'm sorry for my fault, in part I mean. IMHO the all unread messages should keep the date order as sorted and not keep the unread first. This way would avoid this mistake once we have the filter "unread" and I would filter just the unread messages. Or maybe have some option in admin to keep the unread first or not. Do we have such setting in the admin?
Thanks again and I'm sorry about that.
