I have 2 laptops, 1 runs windows 7, with Outlook 2010, the other XP, with Outlook 2007. Both have been fine until recently. Now when i send an e-mail with an attachment of any size, small or large, i get an error msg: "your message was not able to be sent because the connection to the server was interrupted". This happens occasionally with e-mails that have no attachments but if i resend it will go. Not so with attachments
