outlook will not send attachment, but intermidently, no rhyme or reason,send some , doesnt send others

hi, we've got a system, win xp pro, sp2, with ms office 2003, with outlook
2003, and the office sp3...
howeve, when the user sends out email with attachments, the mail goes thru
the send/rec process ,but then gives a timeout error, timeout connecting to
smtp server...
however, it does send out other attachments, and mail, otehrs can send out
that same attachment, with same system/outlook...
it doesnt matter the type of file, whther its a .jpg, .zip, whatever, it
just sits in the outbound box, wont go out.
ideas?
i tried to turn off the firewall, disable the anti virus, added the
outlook.exe to the windows firewall exception list...
ideas?
thanks
marc

Greetings, MarcHelfand !

1. Check if antivirus email check is slowing sending.  Disable it.

2. In the account settings, Advanced settings, change the server timeout time from 1 min to 10 min

3.  Check with Tech Support if the email service server is having trouble.

Best wishes!

Go to Tools > Accounts and go into the email service account settings (if you are using Earthlink, go into Earthlink settings).  Go to Advanced tab.  The server timeout time is set there.
