Do you have the FWC / TMGC installed on the client?

If not, does it use TMG as the default gateway and a DNS server that can
resolve public names?

Any help?


 I am currently using Outlook 2007 for my Verizon.net email which uses
POP3/SMTP for incoming and outgoing mails respectfully . I recently
installed and configured Forefront TMG 2010 firewall on my network. Web
Access Rule has been configured and all machines on my home network can get
on the Internet fine. I have confirmed that the POP3 and SMTP settings are
correct. They've been working fine before I installed the TMG 2010. 

I used to have ISA 2006 and I remember that when I first configured it on my
network, I didn't have to configure anything thing with the exception of the
Web Access rule for my Verizon email in Outlook to work out fine. 

Now the problem is when I tried to send email from Outlook 2007, I receive
the error:

Error message - Sending' reported error (0x800CCC0D) : 'Cannot find the
e-mail server. Verify the server information in your account properties"

Now I cannot send and cannot receive any e-mails. 

I have verified the e-mail server with Verizon support. I have even created
another access rule for POP3 & SMTP from the External network to the
Internal network and this thing is still not working. 

Any help will be appreciated very much.
