SYMPTOMS
When you try to add a new entry to the
Mailing Lists tab in the properties for the Connector for POP3 Mailboxes component of Small Business Server (SBS) 2000, you may receive the following error message:
The e-mail address already exists.
Enter a new address.
To close the dialog box, the only option is to click
OK, and then remove the new entry. However, when you reopen the properties for the Connector for POP3 Mailboxes, the original entry as well as the duplicate mailing list entry may have both been removed.
You may also see this behavior if you edit the duplicate entry to a unique set of values, and then save the entry. Both the edited entry and the account that was originally duplicated may be removed.
Attempting to add duplicate user mailbox entries does not exhibit the same behavior.
