Occasionally a private message that I 'send' sits in the Outbox section of the site. It just doesn't send for a while. What is going on here? On other occasions it goes immediately, or in a minute or two. But one that I sent around 9 this morning is still stubbornly sitting there in the Outbox, two hours later.
There is plenty space in the 'sent items' section, and in the others; they are all less than 50%.
Is this a fault? User error? Or is there a wee trick I can use to get this message sent?
TIA
Mary
