My company will be migrating from GW 5.5 to Exchange 2003 within the next few months. We feel the migration will be smoother if we can get the Outlook 2003 client on the workstations, get the end-users used to the new client, etc. I have not been able to get Outlook 2003 to work with GW 5.5 or GW 6. I tried configuring it using the "other server" option. Outlook will not launch and then I have problems getting GW to open. A couple of months ago, I was able to get Outlook 2000 to work, and I had my address books. My boss does not want to roll out Outlook 2000 and then after the Exchange migration, upgrade the clients. Please let me know if you have any suggestions on how I could make Outlook 2003 work. I appreciate your help very much!
