Hello:

I am running Outlook 2003, Vista Home Premium, and Windows One Care over a
dsl connection to AT&T/SBC.

Everything worked fine until about 10 days ago when I began receiving
intermittent errors when sending or receiving e-mail. I finally had to
switch to manual send/receive just to control number of failed attempts. I
made no other changes on any of my settings. Eventually, after several
passes on each occasion, I could retrieve and/or send e-mail.

Today, I can no longer send e-mail at all, no matter how often I try. I get
error message that smtp server not responding. I've gone on line via web
interface and confirm I can send and receive e-mail from this account.

I just wasted an hour + with AT&T/SBC tech support who confirm all of my
server settings are correct, but can not diagnose error. They claim there
are no problems on server and contend it is a software problem.

Any suggestions?

Many thanks!
