I would guess this could be an issue with the mail servers. Is your isp the host of the POP3 accounts? Or is this from another service provider?

Hello<br />
<br />
i have recently setup sbs 2003 server with 4 client computers.<br />
<br />
each of the computers is now connected to the network and has internet access.<br />
<br />
however each of the client computers has outlook installed and has an external pop3 email account. &nbsp;but now all clients are receiving an error when trying to set up emails. &nbsp;the outlook test shows that they successfully log onto incoming and outgoing servers, but fail on send and receive emails.<br />
<br />
is it possible that the server is blocking this traffic.<br />
<br />
i have not attempted to set up to allow emails and would appreciate any help in doing so.<br />
<br />
<br />
<br />
thank you

Small Business Server (SBS) is a line of server operating systems targeted at small businesses by bundling the operating system with a number of other Microsoft products that would normally need to be purchased or licensed separately. The most notable inclusions are Exchange, SQL Server, SharePoint and ISA/TMG (Microsoft's firewall and proxy server).
