I have recently Exchange 2003 on DMZ .When I try to add the Exchange service to any existing user (running Outlook 2003) I can resolve the user's mailbox on the Exchange server, as long as I don't change the data store to the Exchange mailbox (ie leave as Personal Folders). If I try to change this, I get the following message "The specified default store could not be opened. Please make sure you can access your default store and try again". If I try to resolve the exchange properties of the newly created user, I get an error message saying outlook is offline.
The only way for users runing OL 2003 is to get their mail via OWA, and there is no problem at all.
Other users in same domain running Office XP they do not have any problem at all, they can receive/send mails.
Can someone help me out to resolve this problem
Waiting for your reply, and many thanks.
All the Best
