Please follow the steps listed below.
- On the Tools menu, click E-mail Accounts.
- If View or change existing e-mail accounts is not already selected, click View or change existing e-mail accounts, and then click Next.
- Click on your WebHostForASP mail account, and then click Change.
- In the Internet E-mail Settings (POP3) dialog box, click More Settings.
- Click to select the My outgoing server (SMTP) requires authentication check box.
- Ensure that Log on to incoming mail server before sending mail is selected. This assumes that you have told Outlook that your account is a POP3 account, instead of IMAP. If IMAP is used, the radiobutton will not be there - please see below for workaround.
- Click OK, click Next, and then click Finish.
- Quit and restart Outlook before you send mail.
You can then continue to use Outlook Express as you regularly would.
For Outlook using IMAP:
a. The workaround is to ensure that Outlook is schedules to send and receive mail every n minutes, with n < 30 minutes.
b. By default, Outlook is not configured to send/receive every n minutes. You must configure this.
c. Go to: Tools | Send/REceive Settings | Define Send/Receive Groups
d. Select "All Accounts"
e. Use the checkbox: Schedule an automatic send/receive every n minutes
More Information
This setting configures Outlook to re-authenticate to your POP or IMAP account, which authenticates your access to our SMTP server.
