SYMPTOMS
If a user tries to access Exchange 2000 by using Microsoft Outlook Express with the Post Office Protocol version 3(POP3) protocol, the user may receive the following error message, where AliasName is the Exchange 2000 alias name and ExchangeServerName is the name of the Exchange 2000 server:

There was a problem logging onto your mail server. Your Password was rejected.

Account: AliasName on ExchangeServerName, Server: ExchangeServerName, Protocol: POP3, Server Response: '-ERR

Logon failure: unknown user name or bad password.', Port 110, Secure(SSL): No, Server Error: 0x800CCC90, Error Number: 0x800CCC92



CAUSE
This behavior may occur if the Exchange 2000 e-mail alias for the user account is different from the Microsoft Windows 2000 user name for the account.



RESOLUTION
If the e-mail alias for the user account must be different from the Windows 2000 user name, you must configure a new e-mail alias as the default e-mail address for the account, and then configure Outlook Express to use it.

NOTE: Complete the procedures that are described in this section only if the user requires the logon format of NTDomain\NTDomainID.

To modify the default SMTP address for the user, follow these steps:
 * 1) Click Start, point to Programs, point to Administrative Tools, and then click Active Directory Users and Computers.
 * 2) Double-click Users.
 * 3) In the right pane, right-click the account that you want to modify, and then click Properties.
 * 4) Click the General tab, and then type the full e-mail address for the user in the E-mail box.
 * 5) Click the Account tab, and then type the Windows 2000 user name in the User logon name box.
 * 6) In the User logon name (pre-Windows 2000) box, type the pre-Windows 2000 user name.
 * 7) Click the Exchange General tab, and then type the Windows 2000 user name from step 5 in the Alias box.
 * 8) Click the E-mail Addresses tab, click New, click SMTP Address in the E-mail addresses list, and then click OK.
 * 9) In the E-mail address box, type the address that you want to use as the user's default address, and then click OK.

NOTE: This address must include the domain suffix.
 * 1) Click the address that you entered in step 9, and then click Set as Primary.

To remove the original SMTP address, follow these steps.

NOTE: The following steps are optional. Complete these steps only if no e-mail is sent to the original SMTP address.
 * 1) Click the original SMTP address in the list, and then click Remove.
 * 2) Click Yes to confirm the removal, and then click OK.
 * 3) Quit the Active Directory Users and Computers snap-in.

To configure Outlook Express to use the new SMTP address, follow these steps:
 * 1) Start Outlook Express.
 * 2) On the Tools menu, click Accounts.
 * 3) Click the Mail tab, click the user account, and then click Properties.
 * 4) In the E-mail address box, type the SMTP address that you entered in step 9 in the first procedure that is described in this section.
 * 5) Click the Servers tab.
 * 6) In the Account name box, type Domain\Username, where Domain is the domain for the account and Username is the Windows 2000 user name.
 * 7) In the Password box, type the password for the Windows 2000 user account, and then click to select the Remember password check box.
 * 8) Click OK, and then quit Outlook Express.
