Unable to send emails with attachments in Outlook Express

[Tony Donato]

I have been stumped. I have a PC in my home which I am unable to send emails
with attachments in Outlook and Outlook Express. I bring the PC to my office
and it works. I have a Linksys Router and use Optimum Online is my ISP at the
office. At home I have a DLink Router and Optimum Online is the ISP. At home
I am able to send emails with attachments from a different laptop. I have
disabled the outgoing email scan feature in my Antivirus software (Avast) and
have also completely disabled the program as well to rule out the antivirus
program. I have bypassed the router and tried connecting to the internet
directly to the cable moden to rule out the router as well. What could
possibly be the cause of this? The only difference between my home and my
office is the router. Any clues? Im really lost.

I should also add that I do receive a timeout message that the SMTP Server is
not reachable and the message gives me an option to choose to continue
waiting for a response from the server for an additional 60 seconds. I am
able to send emails without attachments from my home as well.

You don't state was happens when you try You also don't state your version
of Outlook. You should also completely uninstall Avast and reinstall it
without the mail scanning feature. Include in your next post as well
exactly what happens when you use the Test Account button in the account
properties.

Brian,
Thank you for your comment. My version of Outlook Express is 6.0. When I
configure outgoing and incoming server settings and test account settings it
tests successfully. I have uninstalled Avast completely and completely
disabled Windows firewall and still am not able to send email w attachment
from home.

The only thing different between my home and office are the routers. Home is
DLink and office is Linksys. I connected to the internet directly to the
cable modem (Optimum Online is the ISP for both home and office and I have
the identical Motorola Modems in both locations) and still am not able to
send email with attachment so I figured that rules out the router, or am I
missing something?

Could there be a more advanced setting for my NIC card (Linksys) to make it
work correctly with the DLink router?

Any input or guidance is appreciated.

This is an Outlook newsgroup, not one for Outlook Express. I was asking for
you Outlook version, since you said that's having problems. Ask Outlook
Express questions in microsoft.public.outlookexpress.general

Your NIC doesn't care what router is used. Do you have a firewall inside
the router that's not allowing the traffic?

Hi Brian,

No there isnt a firewall within the router. Actually when I send an email
with an attachment from a different PC using Outlook Express and connecting
wireless through the same router I have no problem sending the email with an
attachment. The workstation that is having the problem is hard wired to the
router. Should I install a wireless NIC and see if I still have a problem.
Could that affect my ability to send with an attachment?

Visit the Outlok Express newsgroup, as I said.

Brian,
Solution! It had nothing to do with Outlook. Attachments were sendable
through any computers sharing network with wireless connection but the
subject workstation was connected hardwired. I noticed that the subject PC
was connected to Port #2 on the router. I just moved it over 1 space to Port
#3 and BINGO! It appears that the DLink router does not want you to connect
to the port next to the WAN connector. It wants you to skip one. Similar to
when you Piggy Back Linksys routers from port 8 to port 1, you should not
connect to port #2 etc. I might be babbling but I wanted to share the
solution. Thanks for your time and effort Brian.

Frankly, I'd never had thought to try that. I have used several D-Link
routers, both wired and wireless, and none have ever restricted which data
port I could use.
