Depends a little upon your Internet connection but if you have a slow
connection it may take some time for an attachment that size to spoool. How
many recipients are you sending to? That error often means that your server
requires SSL authentication.

Hi all,

I'm sure what i am missing here. Whenever I try to send an e-mail around
5MB or so, Outlook 2003 says it is sending it and then doesn't. I get a
message saying the following in the 'SEND/RECEIVE PROGRESS' window. I
called my ISP (Shaw) and they said it is my CA Antivirus. So I disabled
it. Still did the same thing. 5 minutes later, the attachment (PDF 6MB)
shows up. I have no idea what is going on. Is there a setting in Outlook I
should be looking for. I never had this problem before.

Task 'shawmail - Sending' reported error (0x8004210B) : 'The operation
timed out waiting for a response from the sending (SMTP) server. If you
continue to receive this message, contact your server administrator or
Internet service provider (ISP).'
and
Task 'shawmail - Sending' reported error (0x800CCC0B) : 'Unknown Error
0x800CCC0B'

Thanks in advance.
Sam
