Outbound mail stopped working. Asking for account ID and Password.

[Bill721]

I have been working fine for a long time receiving and sending emails using outlook 2007 and Iphone.  Last night when I attempted to send an email I got a pop up box "ENTER NETWORK PASSWORD"  I put in the password and it pops right back up asking for it again.  I can't get past the question.    Anyone have any idea what may be wrong.  I even went and changed my password just to make sure, and still the same issue.  It is the same issue on my desktop and my Iphone when I try to send an email.  I'm receiving emails just fine.

I use a Domain mail address for incoming mail and send outgoing mail through my ATT ISP. 

Any help would be appreciated.

I got it fixed.  I had to go into my ATT profile make a change and then save it.  That seemed to reset something and sending emails started working again.  Didn't change anything in outlook or on my Iphone so the problem was with ATT.  The ATT help desk wasn't any help at all......  I hope this helps others....

Could you elaborate a bit for anyone else that might read this thread?

Are you saying you signed into your account from the ATT/Yahoo website?

What profile setting did you change, and was it the first setting you tried, or did you have to try multiple settings before finding one that solved the problem?

The casual word around here, though I haven't seen official documentation of this, is that you have to log in to the webmail or OLAM or something every so often, or mail client logins will start getting rejected. It's supposed to be an attempt to hinder malicious automated mailing.

"Enter Network Password" error occurs, even when Outllok 2007 is being actively used, most every day.

Latest theory is that Basic Yahoo mail does not support Outlook well, and that we should be using the $20/yr Yahoo Mail Plus.

Can you confirm?  No one from ATT ever seems to go intoi these Forums, and officially answer this question.
