SYMPTOMS

Consider the following scenario:
  • You log on to a Microsoft Exchange Server 2007 mailbox through Outlook Web Access (OWA) 2007 by using a user account.
  • You click the user-name button in the top right corner of OWA to open an additional mailbox.
  • Your user account has full access permissions to this additional mailbox.
  • The additional mailbox has a "#" character in the primary Simple Mail Transfer Protocol (SMTP) email address.
In this scenario, a second browser window appears. Additionally, you receive the following error message:

HTTP Error 404.0 - Not Found
The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.
