Hello I am new to the list. I am running Windows 2000 and Microsoft Outlook 2002. Since updating my computer from Windows 98 I have a problem sending emails with large attachments. The email appears to remain in the "Outbox" and never make it to the "Sent" box. It actually does go though! I unfortunately sent someone 27 copies of the same email and attachment :-(( The message I get is Error 0x8004210B Operation timed out waiting for a response from the sending SMTP Server. I don't think it is a problem with my ISP. I did email them (Hotkey that is), but as usual they did not respond. I am not sure what to do next. Kind regards and thank you Jill Riches Strathalbyn South Australia
