I normally send invoices via Sage, through Thunderbird. Normally as I press 'email' on Sage, this message appears 'Another application is attempting to send mail using your user profile. Are you sure you want to send mail?' and there is a tick box to 'Warn me whenever other applications try to send mail from me. I like this alert and it doesn't show anymore (I haven't unticked the box). The emails do send without this warning, but they do not feature in my sent box, which is a big problem for me. How can I make sure my emails show in my sent box? Ideally I would also like the warning message back. Please help, if you can. Best wishes, Sam
