SYMPTOMS

When you use Outlook or Outlook Express and you attempt to check for messages on an Exchange Server-based computer, you may be repeatedly prompted for your user name and password.

CAUSE

Your Post Office Protocol 3 (POP3) or Internet Message Access Protocol 4 (IMAP4) account name does not include the following information:

NTDomain\NTDomainID\ExchangeMailAlias

RESOLUTION

When you use the default Exchange Server POP3 or IMAP4 authentication setting (Clear Text Authentication), set your POP3 or IMAP4 account name to include the following information:

NTDomain\NTDomainID\ExchangeMailAlias

For example, if your domain is "Name_of_domain," your account name is "Myaccount," and your Exchange Server alias is "Serveralias," your account name is:

name_of_domain\myaccount\serveralias

To find your account name in Outlook Express:
  1. On the Tools menu, click Accounts.
  2. Click the Mail tab, and then click your mail account.
  3. Click Properties, and then click the Servers tab.
