If you are connecting via VPN it's possible that something on the VPN is not allowing RPC traffic. Exchange 2000 requires quite a few ports that need to be open in order for Outlook to work properly. I would check technet for an article about firewall and Exchange 2000.

Dear IT fellows, My Exchange server 2k running Win2k has been relocated to another office. The indicated office has a firewall configured to allow full bown Outlook access via a VPN tunnel. My office is able to gain e-mail access via OWA and POP3. However, when Outlook is configured for "Corporate or Workgroup": 1) connection is made to the Exchange server. 2)username is checked, but when launching Outlook the error message pops up: " Unable to open your e-mail folders. The information store could no be opened." I have done the following: 1. Delete and recreate the profile 2. Do a checkname to verify user authentication Please your help is greatly appreciated.. _____ MSN Photos is the easiest way to share and print your photos: Click Here <http://g.msn.com/1HM305401/46> ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: michael.lippman@xxxxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
