This behavior can occur if you have two identical accounts with different names or the Outbox.dbx
file is corrupted.

To resolve this behavior, remove the duplicate mail accounts. To do so, follow these steps:
1. In Outlook Express, on the Tools menu, click Accounts.
2. Click the Mail tab.
3. Click a duplicate mail account, and then click Remove. Repeat this step until only one instance of
the mail account remains.

If the earlier steps do not resolve the behavior, rename the Outbox.dbx file. Note that any items that
remain in the Outbox folder in Outlook Express are permanently deleted after you perform the
deletion. To do so, follow these steps:
