I am using Windows 10 and recently tried to send a photo email from the photo gallery which included a video clip. The result was the following error message - Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity.  Subject 'Norfolk Ramble' Server Error: 421 Server Response: 421 4.4.2 mtaout-mbc02.mx.aol.com Error: timeout exceeded Server: 'smtp.aol.com' Windows Live Mail Error ID: 0x800CCC0F Protocol: SMTP Port: 587 Secure(SSL): No Having removed the video clip all further attempts at sending photo emails enter a queue behind the original offending mail. I believe I need to delete this mail from the outbox, but am unable to locate it, so can anyone please tell me where to find the OUTBOX?
