When you send e-mail in Microsoft Outlook 2000 with the Internet Mail service, the sent message may not leave your Outbox, although you are able to connect and download e-mail.
You have multiple Internet Service accounts in the same profile, and you have chosen to send mail on an account that is not the default outgoing service.
While Outlook supports multiple Internet services for e-mail, you can only specify one as the default delivery account.
Send e-mail using the default e-mail delivery account.
Change the account you wish to use as your default e-mail delivery account.
To use the default delivery account to send e-mail, follow these steps:
On the Tools menu, point to Send and Receive.
Click to select the account at the bottom of the list. This is the default account, assuming you restarted Outlook after setting it as the default.
To specify a different account as the default e-mail delivery account:
On the Tools menu, click Services.
On the Delivery tab, click to select the account you wish to be the default delivery account.
Click the Arrow to the right to move the selected account to the top of the list and click OK.
Quit and restart Outlook.
