I suspect that this problem only happens when you reply to an e-mail that was sent to 1 of the "sub" accounts.

The only way that I have found to handle this, is to pay attention when you are composing a reply to an e-mail and verify that the account shown in the From: line is your primary account.

When you click on reply to an e-mail, OE automatically selects the account that the mail message was sent to as the outgoing account.

If the account that the mail was sent to is NOT the account from the ISP that you are currently logged onto, themail will not be sent.

Do you have any problem sending new mails that you write?

If not, do you have any problems when you reply to mails that were sent to the account that matches the ISP that you are using?

Next, what version of Windows?What IE / OE updates have been installed?
