Contact your email account vendor for details specific to your email account. You may find that to send, you need to use an SMTP config that is slightly different from the POP account you use to receive email.

You would also need to enter the new password in Outlook, if you use that to send email. Here is a guide how to to that:

What version of Outlook are you using?

Hi,

Yahoo mail services are not free, to configure on outlook.

Cancel send recieve and by double clicking on botton right bar or outlook right click the mail on outbook and move to deleted items

Be sure that only one instance of Outlook is running.
You can verify this by openning the tasks manager and ordering process alphabetically.
Kill all redondant Outlook processes.

try turning off the windows firewall or adding an exception for outlook, you can do this from control panel

i am unable to send an email thru my outlook inspite of creating an account. i

Outlook Express is just a software which can send and recieve emails from any email account configured on it(Outlook Express). regardless of yahoo, gmail, comcast.net ,aol.com etc.

So if you want to change your email address and want to use it on outlook express, you need to first create an email account by going to the website on which you want to create an email address.

Once you have created the email address we can look for the POP/SMTP server settings of that particular email account on the internet .
Once we have those(POP/SMTP) addresses we can configure Outlook Express to send and recieve emails for your new email account.

I am recieving some of my emails in my sent box not my inox.I am also using Outlook 2003
