I am operating remotely over a VPN to our Exchange Server. I can reach the folders and inbox by http method to the exchange server, but in Outlook I can not. I can actually send and recieve mails in Outlook, but i can not syncro with the server, and when I click on the various mailboxes I get the message "Unable to expand the folder...information store could not be opened" I am using Windows XP, Outlook 2002, and Cisco VPN. I am pretty sure they are using Exchange 2003 and Windows 2003 as the servers.

Outlook may still be using old Netbios hooks. I solve this issue by creating both a HOSTS and a LMHOSTS file with the exchange servers listed.
If your remote site is DSL, you might also try reducing your MTU size to compensate for the PPPoE overhead.

I have tried to get this answer for over 4 days now. I went through 3 different IT techs to remote into my computer. You are a charm! Wow! It definately was the LMHOsts file that I needed to know.

one thing, i get this problem intermittantly. I have to remove the exchange server link in the properties and "add" it again. Is there something else that is causing this to happen. Now that I have the LMHOSTS on it works when I do that, but seems like i shouldn't have to keep uninstalling the setting in outlook.
Thanks for your help
