This is suddenly a problem on my Outlook 2003 on an old XP PC. I sent an email successfully at 6:35am today (Memorial Day) from my verizon.net account on Outlook 2003 but now (six hours later) cannot send emails on that account from the Outlook 2003. Receive is OK, and a completely different email account works fine in both directions on the Outlook 2003.
I've tried the password generator and incoming emails are OK but still no luck sending.
(If I go to mail.aol.com on my browser, I can send emails. But not from my Outlook 2003.)
Anyone else seeing this today?
