Hi,

Very strange:

I got a few accounts in my Outlook.
Today, I opened Account Settings and click the "Test Account Settings..." button, after finish the progress of Send Test E-mail Message, I got error
"Send test e-mail message: The server responded: 551 User not local; pleas"
or sometimes got error
"Send test e-mail message: The connection to the server was interrupted. If this problem continues, contact your server administrator or Internet service provider (ISP)."

However, I don't remember I got such error for thous accounts before and even now, I can use my Outlook to send and receive Emails without any problem.

Will you think anything wrong in my system? Although I can use Outlook, I still think something wrong in my system since I cannot send Emails by asp.net(c#).

Can you help?
