SYMPTOMS
When you connect to your Microsoft Exchange Server 2003 computer or to your Microsoft Exchange 2000 Server computer by using Microsoft Outlook 2000 or by using Outlook 2002, a large e-mail message may download very slowly or Outlook may stop responding.



CAUSE
This problem may occur if the following conditions are true:
 * Outlook is configured to deliver e-mail to a local personal folder (.pst) file.
 * Many Outlook clients that are configured to deliver e-mail to a local .pst file connect to your server and try to download e-mail at the same time.



WORKAROUND
To work around this problem, configure Outlook to deliver e-mail to your mailbox instead of to the .pst file.

MORE INFORMATION
This problem has been resolved in Microsoft Exchange Server 2003, but only for Outlook 2003.
