outlook 03 and comcast

Hi

We use exchange 2003 for our email with outlook 2003. Are set all have xp. I now have a user that just switched over to comcast Monday and is unable to connect to our exchange server via outlook. The vpn connects just fine. I'm able to get into the network drives. Her web mail works fine. Comcast says its not them. This worked fine before they came out and set her up.

Does your user able to do the telnet to your exchange server?

Comcast might have setup new DLS router or Cable Modem at your user and that might be blocking the ports to your exchange. So in that case you might need to contact them to open/enable the port of the device which they have installed

Comcast put in a modem and a netgear router. They said all the settings are correct. I know for a fact its them somewhere.

How do you telnet? Never done that before. I can log into her computer remotely.
What ports and can i just put them in on her netgear router?

How to Telnet?

open command prompt

Start --> Run --> type cmd and hit OK or press Enter

It would open a black windows (DOS type), in this windows type following:

telnet servername 25

replace the servername with the name of your server (e.g. mail.domain.com) or with IP address of your exchange server

telnet xxx.xxx.xxx.xxx 25

ok great so you are able to connect to your exchange on port 25 so that means port 25 is not block.

now try the same with port 143 (IMAP4) since I am not sure what other ports are involved but I am sure that exchange uses IMAP4

Hi

I tried to telnet to port 143 and it said bye connection refused. connection to host lost.

I think we only use smtp.

Could you try creating a new Outlook profile for the user and see if that works for you?

Or if that does not work, I would recommend creating a new user profile for the user and then create a outlook profile and see if that works.
