XWEB: HTTP/1.0 500 Server Error-The Account Is Currently Locked

Article ID: 173778

Article Last Modified on 10/28/2006



APPLIES TO

  • Microsoft Exchange Active Server Components 5.0
  • Microsoft Outlook Web Access 5.5



This article was previously published under Q173778

SYMPTOMS

When you log on to a client mailbox on an Exchange Server 5.0 computer using a Web browser such as Internet Explorer, the following error message occurs:

HTTP/1.0 500 Server Error (The referenced account is currently locked out and may not be logged on to.)

CAUSE

The user is attempting to log on to an account that is locked by the Windows NT account information. This may be due to logging on with incorrect information a number of times, and thus exceeding the limit set by the administrator for bad login attempts.

WORKAROUND

After you have waited the amount of time set in the lockout duration by the administrator in User Manager for Domains for invalid logins, try logging on again to the Exchange Server computer, or have the Windows NT administrator reset the account information and unlock the account.
